★ Independent bench · no pay-to-rank · OEM & wholesale briefs welcome

For brands, retailers, distributors and OEM buyers

You can buy the test. You cannot buy the verdict.

Put your device through the same five-criteria protocol our readers already trust, licence the measured data behind it, or use our bench to decide what is worth stocking. Built for brand owners, adult stores, marketplace sellers, distributors and private-label or OEM suppliers — with the parts you will not like stated up front.

We don't sell the products we review. Ever. · Are you a brand? Put your device on our bench →

SirenPicks is read by people who are about to spend money on an intimate wellness device — which means it is read by exactly the audience you want reviewing your product. This page sets out precisely what a brand, retailer or distributor can and cannot get from us, including the parts you will not like.

There is no placement to buy here. What you can buy is independent bench time, the measured numbers that come out of it, and the right to cite them with the method attached. What you cannot buy is the verdict.

How does a brand, retailer or distributor work with SirenPicks?

Send a written brief and we reply with a written scope. For a single device that means one unit plus your spec sheet, a run through the identical five-criterion protocol, the measured dataset, a published review with a named tester, and a factual-accuracy window before publication. For sourcing, send the category, volume band, channel and target retail price and you get a ranked shortlist with the measurements attached. In every case the verdict is ours and may be negative — that is the entire product.

  • Nothing is for sale that changes a verdict. No placements, no sponsored posts, no paid rankings, no "partner pick" slot — not at any budget.
  • You get the numbers before publication and may correct a factual error about your own product. You cannot change a score, a verdict or a conclusion.
  • Engagements are scoped in writing before any work starts, and the absence of pay-to-rank is stated inside the scope itself.
  • Negative results are published the same way as positive ones. Several devices on this site carry a negative verdict — that is what makes the positive ones worth citing.

Who this page is written for

Four kinds of buyer arrive here, and they need different things. Find yours — the rest of the page follows that path.

01

Brand owners & DTC sites

You sell your own product and need independent numbers you can put in front of customers without them smelling an advert.

  • A measured review with a named tester
  • Citable figures for your own product pages
  • An honest read on where you lose to a rival, on our head-to-head comparisons
02

Retailers & adult stores

You have limited shelf space and a category full of near-identical boxes that all claim "quiet, body-safe silicone".

  • A shortlist ranked by measured performance
  • Material verification on every pick
  • A list of what we would not stock, and why
03

Distributors & marketplace sellers

You list other people's products on Amazon, eBay, Etsy or a regional marketplace and need to defend every claim in the listing.

  • Measured noise and battery to back a bullet point
  • Body-safety verification for listing compliance
  • Refresh rights when the product is revised
04

Private label, OEM & ODM

You manufacture or private-label devices and want your product assessable on criteria your buyers already trust.

  • Bench time on the identical protocol
  • A measured verdict you can quote in a sales deck
  • Introductions to retailers sourcing in your category

What you receive

Every engagement produces the same four things. They are deliberately concrete, because "coverage" is not a deliverable.

01

The measured dataset

The raw numbers behind the verdict, in a form your product and marketing teams can actually use.

  • Noise in dB at 30 cm, every intensity step, three passes per step
  • Battery runtime to shutdown at a matched step
  • Material verification against your own spec sheet
  • Seal and port condition after ten cleaning cycles
02

A published, citable review

A permanent page with a named tester, a date, a method section and structured data — so search engines and AI assistants can attribute it correctly.

  • Named author and test date, indexed and dated
  • Review and rating structured data on the page
  • Linked from the relevant 2026 roundup where it earns a place
  • Correction policy that protects its credibility over time
03

The verdict, in writing

A short, unambiguous conclusion you can circulate internally. It may not be the one you wanted.

  • Where the device wins, in measured terms
  • Where it loses, and against what
  • Who it is right for, and who should buy something else
  • Value assessment at your real street price, not the RRP
04

A sourceable data licence

For media, marketplaces and retail teams that need numbers they can stand behind in public.

  • Structured, attributable measurements with the method attached
  • Licence terms that survive an audit
  • Refresh rights when your product revises
  • No rewriting of our conclusions — ever

The consequence of the chart above: a brief that cannot state these fields cannot be quoted accurately by anyone.

What each catalogue entry states in writing

Ingress / waterproof rating 9 of 9
Charge time 9 of 9
Motor specification 9 of 9
Electrical ratings 6 of 9
Battery capacity 6 of 9
Measured noise figure 6 of 9
Operating temperature range 1 of 9

3 of the 7 spec lines are published by all 9 catalogue entries; the rest are the lines a buyer has to ask for.

What each catalogue entry states in writing. Counted from the 9 product records this catalogue renders, at build time. Every entry publishes an ingress rating, a charge time and a motor specification; 6 publish a measured noise figure and 1 publishes an operating-temperature range. That unevenness is the normal state of a factory spec sheet, and it is the practical reason to ask for a per-batch test report rather than accept a brand-level certificate: the lines a supplier omits are usually the ones a marketplace or a customs authority will ask you for. Sample turnaround runs 3–5 business days before any production clock starts.

How an engagement runs

Five steps, written so there are no surprises at step five when the verdict is not what you hoped for.

Two decisions happen inside those steps and both are worth naming before you send anything. The first is whether the sample you receive is destroyed or merely handled — a destruction-test sample is the only one that shows you the core, the motor mount and the seam, and it is the step most buyers skip because the unit looks fine and the timeline is tight.

The second is whether the payment terms on the table are first-order terms or second-order ones. Net-30 is earned after a clean first shipment, not before it: a supplier who offers it on day one is either financing you through a higher unit price or has not priced the risk at all, and both are answers.

  1. 1

    Send the brief

    Tell us the device, the market and what you need to know. If you are sourcing rather than submitting, tell us the category, the volume band and the retail channel.

    Handled by the partnerships desk, not by the testers who write verdicts — so no verdict can be traded for a deal.

  2. 2

    We scope it in writing

    You get a written scope: which tests apply, what you will receive, what it costs if anything, and the explicit statement that the verdict is ours to write. No scope, no invoice, no exceptions.

    Most engagements are scoped within two working days.

  3. 3

    The device runs the protocol

    The same five tests as every device on the site: noise at 30 cm, timed battery, material verification, cleaning durability and value at street price.

    Devices are bought, sampled, or supplied subject to the disclosure rules on our disclosure page.

  4. 4

    You get the numbers first

    Before publication, we send you the measured data and give you a factual-accuracy window: you may correct a specification or a claim about your own product. You may not change a score, a verdict or a conclusion.

    This window exists to reduce factual errors, not to negotiate outcomes. Abusing it ends the engagement.

  5. 5

    It publishes, dated and attributed

    The review goes live with a named tester, the measurement date, the method link and the ownership disclosure. Negative outcomes are published exactly like positive ones.

    You are told the publication date in advance. There is no embargo on a negative verdict.

Before you promise a launch date, check whether the calendar you are promising against has any slack left in it.

A realistic first private-label timeline (working days)

Sample from a stock platform 3–5 days
Bulk after sample approval 25–35 days

Highest in this set: Bulk after sample approval at 25–35 days.

A realistic first private-label timeline (working days). The two legs of a first order, in working days, from the lead-time bands manufacturers post for B2B buyers in 2026. A sample from an existing mould typically arrives in three to five days; bulk production then runs 25–35 days after the sample is approved. Freight and customs sit on top, which is why the honest planning number from brief to delivery is two to three months — and the delays almost always land in the leg founders assumed would be quick.

Work this backwards from the shelf date rather than forwards from the order date — the arithmetic only looks comfortable in one direction.

What stands between a purchase order and a shelf date

Sample round and approval 10–15 days
Production after sample approval 25–35 days
Sea freight to a major port 25–38 days
Marketplace or 3PL check-in ~7 days

Fastest realistic path is 67 days and the long one is 95 — which is why a December shelf date means an order placed by late August.

What stands between a purchase order and a shelf date. Published ranges for this category, stated as ranges: a sample round takes 10–15 days, production runs 25–35 days after the sample is approved, a sea leg to a major port adds 25–38 days, and marketplace or 3PL check-in adds about another week. Added up, the shortest realistic path from purchase order to shelf is 67 days and the longest is 95. Working back from the shelf date is the whole point: an order placed in October for a December peak lands after the peak it was meant to catch. Air freight compresses the middle leg at a cost that usually exceeds the margin it protects, so the calendar is the constraint, not the freight mode. Figures are planning ranges, not a quotation, and every supplier's clock differs.

What to send with your brief

The difference between a scope and a week of email is usually one document. Here is the list — and what we do when you do not have something, because most people do not have all of it.

What to send with your brief — and what happens if you do not have it
What to sendWhy we need itIf you do not have it
The device itself (or a retail unit)We test the unit a customer would receive, not a golden sample.Tell us the model and market; we will buy it at retail and disclose that we paid for it.
The current spec sheetMaterial verification is checked against your own published claims, so we test what you promise.We will verify the material physically and mark anything we cannot confirm as unverified.
Any compliance documentation you rely onIf your listing claims CE, RoHS, REACH, FDA or an ISO quality system, we ask to see the document rather than repeat the badge.We will say plainly in the review which claims we could not verify — that protects you as much as us.
Packaging and channel detailsRetail packaging, discreet shipping and marketplace listing rules change what a buyer actually receives.Useful but optional; it mainly affects the sourcing shortlists, not the bench test.
For sourcing briefs: category, volume band, channel and target retail priceIt decides whether a device is realistic at your margin — the single most common reason a shortlist fails.Volume band and channel are the two we cannot work without; give us those first.
Any MOQ, lead-time or private-label constraints you are working toIt separates a device you can actually stock from one you can only admire.Optional. It matters for sourcing and OEM introductions, not for a bench test.

Start here: no amount of price negotiation rescues a certificate pack that is incomplete for the destination market.

The certificate pack a B2B buyer must clear, by market

European Union 4 documents
United States 2 documents
Japan 2 documents
United Kingdom 1 document
Australia / NZ 1 document

Highest in this set: European Union at 4 documents.

The certificate pack a B2B buyer must clear, by market. A count of the documents an intimate-wellness OEM typically needs per market before goods clear a border or a gated marketplace. The EU carries the heaviest load — CE covering the Low Voltage and EMC directives, RoHS, REACH, plus an EU-established Responsible Person under the GPSR — and any device with a lithium cell needs UN38.3 and IEC 62133 again in every market. We flag these in every sourcing shortlist, because a device that cannot clear a border is not one we will recommend for a cross-border programme.

Engagement options

Most requested

Independent test & review

Device brands and distributors with a product they want measured by someone with no stake in the answer.

  • Full five-test protocol on one device
  • Measured dataset plus published review with a named tester
  • Factual-accuracy window before publication
  • Inclusion in a roundup or face-off where the device earns it
  • The verdict is ours, in full, including when it is negative

This is not a paid placement. Where a fee applies it covers bench time and the licence to cite the resulting data, and it never buys a score.

Send a brief

Retail & distribution sourcing

Retailers, distributors and marketplaces that need to decide what is worth stocking in a category full of near-identical listings.

  • A shortlist of devices that cleared our material check
  • Measured noise, battery and value per dollar, side by side
  • Ranked by the criterion your buyer cares about, not by margin
  • A visible statement of anything you sell that we would not stock

We do not sell the products we review, so the shortlist is not a pitch for our own catalogue.

Discuss sourcing

Data licensing & partnerships

Media, marketplaces and platform teams that need measured, attributable numbers rather than rewritten marketing copy.

  • Structured measurements with the published method attached
  • Attribution and licence terms that stand up to an audit
  • Refresh rights when a product is revised
  • Our conclusions are licensed as written, never re-cut

We will decline a licence if the intended use would present our data in a misleading way.

Talk to us

This is the line first-year plans leave out, because it appears on the payment processor's statement rather than on the factory's quote.

Payment-processor reserve a high-risk merchant should price in (%)

CCBill / SegPay reserve ~5–10%
Epoch / Verotel reserve ~5–10%
Stripe / PayPal high-risk hold up to 15%

Highest in this set: Stripe / PayPal high-risk hold at up to 15%.

Payment-processor reserve a high-risk merchant should price in (%). Rolling reserves charged by processors that actually clear intimate-wellness merchants, held for 90–180 days before release. Specialist high-risk processors (CCBill, SegPay, Epoch, Verotel, PaymentCloud, Durango) run a ~5–10% reserve on top of a 4–15% discount rate; mainstream processors generally decline the category outright and, when they detect it, terminate with a 90–180 day fund hold. The reserve is the line that most often breaks a first-year cash-flow plan if it is not modelled up front — treat it as trapped working capital, not a fee. Published ranges for this category, not a quote for any single account.

Why brands work with us anyway

  • A negative result is still useful. If your device is loud at the low setting or the seal fails after ten washes, you need to know before your customers do. We will tell you what we measured and where it lost.
  • The audience is qualified. Our readers arrive from roundups and face-offs with a constraint and a budget. They are not browsing — they are choosing.
  • The method makes your result defensible. Because the protocol and the weights are public and identical for every device, a good score is something you can cite rather than something you have to explain.
  • A citable number outlives a campaign. An advert stops the day the budget stops. A measured, dated figure in a published review keeps working on your product page and in your marketplace listing.
  • Supply-chain buyers already need this. Distributors, marketplace sellers and procurement teams have to defend every claim in a listing. Data with a published method behind it is the shortest route to that.
  • We are blunt about our own conflict. We own our own line and we say so on every page. That transparency is the reason a positive verdict from us means something.

The channel math comes before the product

Most sourcing briefs we receive start with a device. The ones that survive contact with a buyer's spreadsheet start with a channel, because the channel decides the order size, the order decides the tooling, and the tooling decides whether the unit price you were quoted is even available to you. Get that order wrong and a perfectly good product becomes unstockable at your price point. A market-size number belongs in the same paragraph and one step further back: the sexual wellness market 2030 projections that circulate in pitch decks describe a category, not your niche, and none of them tells you whether a channel can absorb 300 units a month.

What each channel actually costs, and where it breaks
ChannelWhat it costs youWhat it buys youWhere it breaks
Direct-to-consumerEvery unit of demand is paid for: CAC, fulfilment, returns, payment-processing risk on a high-risk merchant codeThe full retail margin and the customer relationship, plus the sell-through data every later channel will ask forIt does not scale past the ad account. Platforms restrict this category, so paid acquisition is the constraint, not product
Distributor20–60% of the unit price sits between you and the factory, depending on how many tiers are in the chainSmaller minimums, stock on the shelf today, and someone else carrying the import and warehousing riskYou sell the same public-mould product as everybody else in the chain, and your competitor buys it from the same place
Retail chain (wholesale)40–55% off suggested retail, minus landed cost; freight to their warehouse is yoursVolume commitment and a placement that does more for credibility than any advert you could buyNet 30–90 terms: the order that grows your revenue can run your cash flow dry before the invoice clears
Marketplace (Amazon, regional)Referral fee, fulfilment fee, and a listing that can be suspended overnightDiscovery without a brand, and the review volume later channels want to seeConcentration risk — one ASIN is not a business, and compliance documents get requested
Clinical / professionalCredential gating, clinic-ready packaging, patient-education material, and a much stricter claims rulebookThe highest trust per sale and the least price sensitivity, because the recommendation comes from a professionalYou cannot market your way in. It is a relationship channel and it moves at the speed of procurement

Two numbers decide whether a wholesale order is a business or a cash trap. The first is the gross margin: retail chains typically buy at 40–55% of the suggested retail price, which is materially thinner than direct-to-consumer — but it arrives without a customer-acquisition cost attached, and that is usually the trade you are actually making. The second is the payment term.

Net 60 is ordinary for a mid-size chain, and Net 90 is not unusual, which means a $50,000 order book can leave $35,000–50,000 sitting in accounts receivable for two months while your factory was paid 30% up front and the balance on shipment. That gap is funded from your own balance sheet, and it is the single most common reason a brand that was growing fast stops being able to buy stock.

Volume tiers are where the margin gets rebuilt. Published wholesale structures in this category typically step a few points at the 500-unit break and again past 1,000 — small enough to look trivial, large enough to decide whether a promotion is affordable. Ask for the tier table in writing before you negotiate a price: a supplier who will not publish the break points is telling you the tiers are set per conversation.

The cash question is not "what is the unit price" but "what does the step cost me". Moving from 1,000 to 5,000 units on the same product multiplies the order value by roughly three while the unit price falls by about a third — the tooling is already paid, so the whole delta is inventory and working capital, and it lands before a single unit sells. A retail buyer rewards that step with a better margin; your balance sheet has to survive it first. Model the 5,000-unit order against your own collection terms rather than the factory's, and the honest answer is often a 2,000-unit order placed twice.

If your buyer is a retail chain, EDI is the entry ticket

Electronic data interchange — the system-to-system exchange of purchase orders and invoices that most large retailers require from suppliers (see the Wikipedia entry Electronic data interchange) — is not a technical nicety. It is a gate. A supplier who cannot acknowledge an order and send an advance ship notice in the retailer's format does not get onboarded, regardless of the product.

Five documents carry almost the whole relationship: the 850 purchase order in, the 855 acknowledgment and 856 advance ship notice out, the 810 invoice, and the 846 inventory advice that stops a buyer ordering stock you do not have. Onboarding through a network provider is typically quoted in weeks rather than days, so it belongs in the launch plan, not in the first week after a purchase order lands.

What retail compliance failures cost, and why they happen
Compliance failureTypical chargebackWhat actually caused it
Missing or wrong carton label$50–150 per cartonLabels printed from the purchase order instead of from what was packed
Advance ship notice error$100–300 per shipmentThe ASN is built from the order rather than from the scanned cartons
Pallet non-compliance$50–100 per palletPallet spec is in the routing guide, which nobody read past page two
Missed delivery windowA percentage of the PO valueThe appointment was booked after the goods were ready, not before

None of those penalties are product problems. They are documentation problems, and they all trace back to one habit: building the paperwork from what was ordered rather than from what was actually shipped. A factory that gives you per-batch test reports and a packing list that matches the cartons is doing the work that keeps you out of that column. Each of those four failures, the dates that cause them and the planogram check that comes after are written out on retail readiness, and the arithmetic that decides whether a reorder follows is on the second order, and the arithmetic of the ending — a delisting, a markdown, a dead SKU — is on the shelf-exit checklist.

The clinical channel is a different product, not a different price

Pelvic-health physiotherapists, urology and gynaecology practices, and pharmacies that stock a wellness line buy differently from an adult retailer: they need a professional account with credential verification, clinic-ready packaging, patient-education material, and a claims rulebook that forbids outcome guarantees. The categories are organised around areas of care — pelvic floor, vulvar and intimate care, menopause comfort, prostate and male pelvic health — rather than around the retail taxonomy.

If you want that channel, the assortment decision comes first and the product decision second, which is the reverse of how most brands approach it. We will tell you plainly in a shortlist when a device is consumer-only, because a device that cannot survive clinical packaging and claims discipline is not a clinical product at any margin.

The channel decision comes before the product decision, because it sets the order size the whole cost stack is built on.

What each retail channel actually orders, per SKU

Independent boutique 12–24 units
Regional adult chain 50–150 units
National chain (EU/UK) 200–500 units
Pharmacy / mass retail 500–2,000 units

A national chain's first purchase order starts at roughly the point where a private-label tooling run becomes economic — which is why channel choice and tooling choice are the same decision.

What each retail channel actually orders, per SKU. Typical per-SKU purchase quantities by retail channel, from published wholesale guidance for this category rather than from our own orders. Read it against the factory minimums on the catalogue page: a boutique order of 12–24 units cannot absorb a private tool, a national chain order of 200–500 can, and pharmacy-scale volumes are the only ones where a custom mould is unambiguously the cheaper route. A distributor sits between the two ends of this table and will quote you a smaller number at a higher unit cost — that spread is what they are paid for.

Sizing context, not a forecast: it tells you whether a niche is worth a business, not whether your product will sell in it.

Intimate-wellness market size a new brand enters (USD bn)

2026 $36.49B
2027 $39.73B
2028 $42.96B
2029 $46.20B
2030 $49.43B
2031 $52.67B

The global intimate-wellness market was USD 36.49 billion in 2026 (Mordor Intelligence) and is forecast at USD 52.67 billion by 2031 — a 7.61% compound annual growth rate. Three independent research houses now bracket 2026 between USD 36.5 billion and USD 42.8 billion and project roughly 8% CAGR through the mid-2030s, so the slope, not any single headline, is the planning figure.

Intimate-wellness market size a new brand enters (USD bn). Mordor Intelligence sizes the global sexual wellness market at USD 36.49 billion in 2026, rising to USD 52.67 billion by 2031 at a 7.61% CAGR. The 2027–2030 bars are interpolated from those two published endpoints, not separately sourced, and are shaded in the source as such. A second research house (Research and Markets) puts 2026 at USD 39.9 billion, and two more (MarkWide Research, Cognitive Market Research) bracket 2026 at USD 41.8–42.8 billion and project roughly 8.2% CAGR to USD 82–85 billion by 2034–2035 — all four point the same direction: steady, not explosive, growth. Within the category, medical-grade (platinum-cured) silicone is the fastest-growing material segment at about 10.8% CAGR, and online retail already accounts for roughly 45% of the channel. Plan capacity on the slope, not on a headline number; the products have moved from an "adult novelty" aisle into intimate wellness and self-care framing, led by female and Gen-Z consumers.

For retailers, distributors, marketplace sellers and OEM buyers

If you are sourcing rather than submitting, the useful thing we sell is a decision: which devices in your category are actually body-safe, actually quiet, and actually worth the shelf space. Tell us the category, the volume band, the channel and your target retail price, and we will send a shortlist with the measurements attached — including the devices we would not stock and why.

That shortlist is built for the questions a supply-chain buyer actually has to answer:

What a sourcing shortlist actually answers
The question you have to answerWhat we provide
Is the claimed body-safe silicone real?Material verification on every shortlisted device, flagged as confirmed or unverified. Nothing unverified is recommended.
Will customers return it because it is loud?Measured low-setting noise in dB at 30 cm — the figure that predicts returns better than any "quiet" claim.
Does the battery survive past week one?Timed runtime to shutdown, plus how the final 20% behaves when it starts dying mid-use.
Can I defend this listing to a marketplace?Measured figures you can cite, with the published method attached, so a compliance reviewer sees a source rather than a slogan.
Is it worth the shelf space at my margin?A value score against your target retail price, not against the launch RRP.
Can I actually stock it?For sourcing briefs we work from your MOQ, lead-time and packaging constraints, and we say when a device is unrealistic at your volume.
What should I delist?A do-not-stock note on anything in your range that failed our material check or scored badly, with the measurement that decided it.

If you need manufacturing introductions rather than opinions, we will connect you with manufacturers whose product has survived the bench — including private-label and OEM/ODM producers where relevant to your brief. We take no commission from either side of that introduction, which is the only way the introduction means anything. What happens after the introduction — MOQ by route, who owns the tool, whose name is on the CE declaration — is set out in full on the OEM and private label page.

Each row is a question you can ask before money moves; each one you skip becomes a question you ask after it has.

Signals to gather before a first deposit

Business licence + 18-digit credit code 1 signal
Live, unscripted video walk of the floor 1 signal
Sample made on production tooling 1 signal
Batch-level test report, not model-level 1 signal
Invoice beneficiary matching the licence 1 signal
Third-party audit (above ~$10,000) 1 signal

Six independent signals before a first deposit: licence and credit code, a live video walk, a sample made on production tooling, a batch-level test report, an invoice beneficiary that matches the licence, and a third-party audit above roughly $10,000.

Signals to gather before a first deposit. Each check rules out a different deception, which is why no single one is sufficient: the licence catches a company registered for the wrong scope, the live walk catches an office posing as a plant, the production-tooling sample catches a hand-finished mock-up, the batch report catches a certificate bought once for a model rather than tested per run, and the beneficiary check catches payment redirection. The audit is last because it is the most expensive and the hardest to stage around. Skip one and the specific fraud it was designed to catch is the one you meet.

The recurring half of this bill — EDI subscription, insurance renewal, prefix renewal — keeps arriving after the listing goes live.

What a retail listing costs before the first purchase order ships

Retail-ready packaging + artwork $1,000–5,000
GS1 company prefix (own barcodes) $250–2,500
Product liability cover (year one) $500–2,000
Vendor agreement legal review $500–2,000
EDI provider setup $0–2,000
GS1-128 label printer $300–1,500

Published vendor-onboarding ranges put the total at roughly $3,000–12,000, spent before a single extra unit is produced — and the recurring half (EDI subscription, insurance renewal, prefix renewal) is the part that keeps costing after you are listed.

What a retail listing costs before the first purchase order ships. The one-time cost stack a brand pays to be onboarded by a retail chain, with planning midpoints drawn from published vendor-onboarding ranges for US and EU retail. Retail-ready packaging and artwork leads, because a direct-to-consumer pack usually fails case-pack, label and pallet specifications; own GS1 barcodes come next, since a resold prefix is rejected at item setup; product liability cover and a legal review of the vendor agreement are entry conditions, not optional extras; EDI setup and a GS1-128 label printer are the technical gates. The total runs $3,000–12,000 before any additional inventory, and it sits outside the unit price, the freight and the certification pack. Bars are a planning midpoint, not a quotation — the ranges, not the midpoint, are what you budget.

Four to eight weeks of this clock is EDI alone, which is why the technical setup sits on the critical path rather than at the end of it.

Days from buyer approval to a dock-ready first order

Approval → first PO → dock receipt 30–90 days
EDI / supplier-portal onboarding ~28–56 days
Retail-ready artwork + packaging ~21–45 days
Vendor setup + document pack ~14–30 days

The buyer saying yes starts a clock, not a shipment: EDI onboarding alone runs four to eight weeks and sits on the critical path, which is why it belongs in the launch plan and not in the week after the purchase order lands.

Days from buyer approval to a dock-ready first order. How long each stage of retail onboarding takes, in days, from the point a buyer approves a brand to the point a first order can physically reach a distribution centre. EDI and supplier-portal onboarding is the critical path at roughly four to eight weeks; retail-ready artwork and packaging runs three to six weeks and can overlap it; vendor setup and the document pack is two to four weeks; the whole sequence lands at 30–90 days end to end, and complex retailers sit at the far end. None of this overlaps with production, sea freight or customs, so a shelf date quoted from the order date rather than from the approval date is already late. Ranges are planning figures for the category, not a commitment from any retailer.

Each document is issued by a different authority and the responsibility sits with a different actor — which is why one certificate never covers another.

Material compliance documents: who issues them, who is responsible

ISO 10993 biocompatibility test battery ISO + lab
USP Class VI (plastics contacting fluid) USP
FDA establishment registration — MoCRA (21 U.S.C. 364a) FDA
CE / EU MDR technical file Notified Body

Four material-compliance documents, each issued by a different authority (ISO and an accredited lab, the USP, the U.S. FDA, an EU Notified Body) and owned by a different responsible party (the manufacturer, the material supplier, the U.S. agent, the manufacturer).

Material compliance documents: who issues them, who is responsible. The ISO 10993 biocompatibility test battery is performed by accredited third-party labs on a device-risk basis and the standard is published by the International Organization for Standardization; the manufacturer holds the per-model report. USP Class VI is a pharmacopeial test of the U.S. Pharmacopeia for plastics contacting bodily fluid; conformance is documented by the material supplier. The FDA establishment registration under MoCRA (21 U.S.C. 364a) is issued by the U.S. FDA and the responsible party is the U.S. agent or registrant when the product is marketed as a cosmetic. The CE / EU MDR_2017/745) technical file is issued by an EU Notified Body and the responsible party is the manufacturer. None of these documents travels with another, and asking for the report with the lab name and a sample ID is the only way to tell a real test from a bought certificate.

Start an enquiry

Six fields and a brief. The partnerships desk reads it and replies with a written scope, not a sales call.

Those answers sit with the desk and are not passed to a factory without your say-so; the retention window for an enquiry thread, and the full list of who else touches it, is on the privacy page.

What happens next: a written scope from the partnerships desk, usually within two working days, stating the tests, the deliverables and — explicitly — that the verdict is ours. If we expect the answer to be negative, we will tell you that before you commit to bench time rather than after.

// R96 — the three works this page cites are cited by the research sub-page // now, and the citation gate refuses an entry that nobody on the page cites. // The bibliography follows the argument: it is on /for-brands/research/.

Everything on this page is sold as measurement, never as a ranking — the desk behind it is SirenPicks, and it publishes its ownership and funding in full. If you want to know who is actually writing your report before you send a brief, the team page names them and states what each one is allowed to refuse.

Questions brands, retailers and distributors ask before they send a brief

Procurement questions included: MOQ and lead time, private label and OEM, confidentiality, marketplace compliance and what happens when a measurement contradicts a spec sheet.

Is trade assurance a substitute for a factory audit?

No, and the two are usually bought by different people for different reasons. A platform trade assurance scheme covers the money: it holds payment against an agreed contract and releases it on the terms you set, which is genuinely useful on a first order. What it does not do is a capability assessment — whether the plant has the equipment, the capacity and the process control to make the thing, whether work is subcontracted, and what its last three defect records actually say. Buy the guarantee for the payment and a third-party audit for the factory; a scheme that protects your deposit tells you nothing about whether the deposit bought what you specified.

What does retail-ready packaging actually require?

More than a nice box. Retail-ready means the case opens into a shelf-ready display without a knife, the barcode on the unit is the retailer's and not yours, the packaging carries the importer's address and the warnings in the language of the market, and the artwork has been through a print proof rather than a screen. Ask for the die-line before you approve anything: a die-line drawn for a different carton is how a logo ends up three millimetres from the trim. Send the printer a vector file rather than a screenshot, and send the die-line with it, because a raster logo is the other way a first print run gets paid for twice.

Can you test a device we already sell, and will you publish it if it fails?

Yes to both. A device submitted to the bench runs the identical five criteria — noise at 30 cm, timed battery drain, material verification, cleaning durability and value — and we publish what the bench says. A catalogue SKU is treated the same way: the numbers behind the A0183 mini wand massager and the A0187 slim bullet massager come off the same equipment as a retail device we bought. What we will not do is soften a verdict in exchange for the fee, which is why the negative reports are the ones worth paying for.

Can I pay for a positive review?

No. There is no mechanism to buy a score, a ranking or a placement, and no sponsored slot on the site. What a brand can pay for is bench time and a licence to cite the measured data that comes out of it. The verdict is written by a tester with no commercial role in the engagement, and negative verdicts are published exactly like positive ones.

What do I actually receive if you test my device?

Four things: the measured dataset (noise in dB at 30 cm per intensity step, battery runtime to shutdown, material verification against your spec sheet, and seal condition after ten cleaning cycles), a published review with a named tester and a date, a short written verdict, and — if you need it — a licence to cite the data with the method attached.

Do I get to see the review before it is published?

You get a factual-accuracy window: you may correct a specification or a claim about your own product before publication. You may not change a score, a verdict or a conclusion, and you cannot approve or veto the copy. Abusing that window ends the engagement.

What happens if my device scores badly?

It is published with the measurements and the reason, exactly as a good result would be. Several devices on this site carry negative verdicts. That is the value of an independent bench: a negative result you can act on is worth more than a positive one nobody believes.

Do you tell brands the publication date in advance?

Yes, so you can be ready for the traffic. There is no embargo on a negative verdict, and publication is not delayed for commercial reasons.

Can you help a retailer decide what to stock?

Yes. Send the category, the volume band and the retail channel, and we return a shortlist of devices that cleared the material check with measured noise, battery and value per dollar side by side — including anything you sell that we would not stock, and why. We take no commission from the sourcing side.

Do you take a commission on OEM or wholesale introductions?

No. We do not take a commission from either side of a manufacturing introduction. If we make an introduction, it is because the manufacturer's product survived our bench, not because there is a fee attached.

Is there a minimum order or a volume requirement?

Not for testing. A single device can be submitted. For sourcing shortlists, tell us the volume band and channel in your brief — that is what lets us tell you whether a device is realistic for your price point at your scale. We work from your MOQ and lead-time constraints rather than assuming a large buyer.

Do you work with private label, OEM and ODM suppliers?

Yes, on the sourcing side. If your brief involves private label or white label production, or OEM/ODM development, we will assess the resulting product on the same bench and can introduce you to manufacturers whose output has survived it. We take no commission from either side of an introduction, so the introduction does not depend on a fee.

Can you help me defend a claim in a marketplace listing?

That is one of the most common reasons distributors and marketplace sellers come to us. A measured figure with a published method attached — low-setting noise in dB at 30 cm, timed battery runtime, verified skin-contact material — gives a compliance reviewer a source instead of a slogan. You also get the method link to cite alongside it.

Will you sign an NDA or keep the engagement confidential?

We will sign a mutual NDA covering unreleased product details and commercial terms. We will not agree to keep a published verdict confidential: if a device is reviewed, the review is published, dated and attributed. If you need pre-launch measurement without publication, say so in the brief and we will scope it explicitly as a private data engagement rather than as a review.

Can we get exclusivity on a category or a comparison?

No. We do not sell exclusivity, and we will not agree to avoid reviewing a competitor. A roundup or face-off that a brand can influence is worth nothing to the reader, which is also what makes it worth nothing to you.

What if the review does not match the spec sheet we sent?

Then either the spec sheet is wrong or the unit does not match it — and you want to know which. If a measurement contradicts your published claim, you get the numbers before publication and a factual-accuracy window to correct the specification. What you cannot do is have the measurement removed, because the measurement is the product.

Do you review devices before they launch?

Yes, if you brief it that way and accept the same rules. The measure is real, the verdict is ours, and any factual-accuracy window is agreed in the scope rather than assumed. A pre-launch negative result is significantly cheaper to act on than a post-launch one.

How quickly can you turn a brief around?

A written scope goes back to the partnerships desk within two working days of a complete brief. Bench time depends on the queue and the test set, and the publication date is agreed in the scope and then treated as fixed — there is no commercial reason we would ever move it.

Do you verify GMP cleanroom and ISO 22716 / GMPC on production lines?

We ask to see the certificate, not the badge. Cosmetic-GMP and ISO 22716 — GMPC being the older US framing — are the quality systems that separate a clean, documented line from a workshop, and we flag any supplier that cannot produce the document rather than repeat the claim. For an intimate-wellness product, the manufacturing environment matters as much as the material, and we will not introduce a factory whose quality system we have not seen.

Can you help with cross-border export and customs compliance?

We flag the export constraints and certification requirements for your destination market — CE, RoHS, REACH, FDA and FCC, plus the HS codes — before you commit to tooling, because that is where good products die in customs. Compliance verification is part of every sourcing shortlist, and a device that cannot clear a border is not one we will recommend for a cross-border (跨境) programme.

What about production capacity and lead time?

Capacity (产能) and lead time (交期) decide whether a factory can meet a launch date, and we separate a device you can actually stock from one you can only admire using your volume band and channel. We will tell you plainly if a factory's capacity is unrealistic for your launch window rather than let you discover it after tooling is paid for.

Do you assess a factory's R&D capability?

Where the brief involves ODM differentiation rather than copy, R&D capability (研发实力) is what separates a product from a me-too. We note whether a manufacturer can iterate on a design or only replicate one, because that determines whether your private-label line can stay ahead of the category instead of trailing it.

Which sales channel should the product be built for?

It depends where you actually sell. Salon and spa (院线) channels want durability and serviceability; e-commerce (电商) want listing-compliant claims and clean imagery; private domain (私域) communities want repeat-purchase potential; cross-border (跨境) wants certification and packaging that survive a border. We tailor the shortlist to your real channel, not the one that sounds most impressive.

Do you identify the source factory rather than a trading layer?

Where we can, yes. Buying from the 源头工厂 (source factory) rather than a reseller removes a margin and a quality-risk layer, and we will name the actual manufacturer in an introduction. Where we cannot verify the factory behind a supplier, we say so — an introduction built on a reseller we cannot trace is not one we will make.

Can you supply wholesale pricing and volume quotes?

We do not set wholesale prices — that is between you and the factory — but our sourcing shortlists establish the realistic price band at your volume and channel, which is what a wholesale quote should be measured against. A quote that sits far above the measured band is a margin red flag, and we will say so.

Discovery & sourcing questions

The questions a first-time buyer types into Google, Instagram, Reddit or LinkedIn before reaching a supplier: how the discovery chain works, private label vs white label, the hottest OEM categories, and how big the market really is.

How do B2B buyers actually find a factory in 2026?

Rarely in one step. The pattern buyers describe is a five-stage chain: a Google intent search ("wellness device China factory", "private label massager manufacturer", "pelvic massager OEM"), then peer verification in Facebook sourcing groups and Reddit threads, then proof — a factory-tour Reel or live production footage on Instagram — then the supplier's own site for terms, then a direct brief. A supplier that only exists at the first step fails the other four. We publish the part of that chain we can evidence: the test method behind every number on this site, and the supplier-vetting sequence for the steps we cannot run for you.

What is the difference between private label and white label for intimate wellness?

Private label applies your brand to an existing mould the factory already owns — the fastest, lowest-risk route, and in this catalogue it starts at 100–300 units. White label goes further and rebrands the app, firmware and packaging so the product reads fully as yours, still from a low minimum. Both run on the same silicone line under NDA; the difference is how much of the product carries your name, not whether it can be built. The wholesale catalogue states what each SKU allows.

Which product types are B2B buyers sourcing most in 2026?

The hottest OEM categories buyers ask about are app-controlled wearable massagers, pelvic massagers, kegel-ball training sets and clitoral suction wands, followed by rabbits, bullets, wands and prostate massagers. The same hot list is what our catalogue already covers, so a brand can launch a private-label line without a new tooling investment — see the wholesale catalogue and the MOQ guide for the entry minimums.

Is Instagram a reliable way to verify a supplier?

It is one of several proof signals, not a verification on its own. Buyers watch factory-tour Reels, liquid-silicone injection clips and per-batch QC videos, then message the same team that posted them — but a video is only worth something if the plant shown matches the business licence. Pair it with the written supplier-vetting sequence: a live walkthrough, a batch-level test report, and an invoice beneficiary that matches the licence. A polished feed plus a mismatched licence is the classic trading-company tell.

Why do B2B buyers cross-check suppliers in Reddit and Facebook groups?

Because the groups are where trading-company scams get named before anyone wires a deposit. Buyers pressure-test a shortlist inside communities like China Sourcing Network, Global Importers Hub and the Amazon FBA Sellers Community, and on subreddits such as r/Entrepreneur and r/Manufacturing. The checks those discussions produce feed straight into our supplier-vetting sequence — the group says "has anyone used them", and you confirm it with documents.

How big is the intimate-wellness market a new brand is entering?

Mordor Intelligence sizes the global sexual wellness market at USD 36.49 billion in 2026, rising to USD 52.67 billion by 2031 at a 7.61% CAGR; Research and Markets puts 2026 at USD 39.9 billion. Both bracket the category and point the same way — steady, not explosive, growth — and the products have moved from an "adult novelty" aisle into intimate wellness and self-care framing, led by female and Gen-Z consumers. The market-size chart on the brands page shows the slope; plan capacity on it, not on a headline number.

Do I need a new mould for a first private-label run?

Usually no. A public tool — a mould the factory already owns — has no new fixed cost to recover, so the minimum is set by the production run alone, and in this catalogue five SKUs start at 100 units and four at 300. A custom colour or Pantone match pushes it to 500, and only a genuinely new shape needs a mould from 1,000 units. The MOQ guide works through the arithmetic, and every SKU states its own minimum in the wholesale catalogue.

How much does it actually cost to launch a private-label device?

More than the unit price suggests. Beyond the per-unit cost, a first order carries six major fixed and semi-fixed lines — tooling, certification, freight, custom packaging, inspection and samples — which together often dwarf the unit-price difference between two suppliers. The wholesale catalogue plots that stack for a 1,000-unit run, and the MOQ guide walks through the arithmetic so the total, not the quote, is what you compare.

What does a retail chain require before it will onboard a brand?

More than a good product. A buyer approves a brand; the vendor-setup, supply-chain and compliance teams then check whether the business can operate inside their systems — own GS1 barcodes rather than a resold prefix, EDI capability for purchase orders, acknowledgments, ship notices and invoices, product liability cover, current certificates, case-pack and pallet data, and retail-ready packaging artwork. Budget roughly $3,000–12,000 in one-time setup and 30–90 days from approval to first shipment, with EDI onboarding on the critical path at four to eight weeks. Both the bill and the clock are plotted on the brands page, and the full sequence sits in §6.5 of the startup guide.

Should a first order go through a distributor or straight to the factory?

Through a distributor when the thing you are buying is certainty, and straight to the factory when the thing you are buying is a product. A distributor sells you stock that already exists, in small quantities, with short lead times and often with the documentation already assembled - which is worth real money on a first order where the risk is not price but the possibility of getting the specification, the paperwork or the market entirely wrong.

A factory sells you a build: your colour, your packaging, your branding, at a unit price a distributor cannot match because there is no wholesale layer, and at a minimum, a lead time and a documentation burden the distributor was absorbing. The decision usually turns on two numbers. If your first order is below the lowest published factory minimum for the shape you want, a distributor is not a compromise, it is the only route that exists.

If your first order is well above it and you intend to sell under your own brand for more than one season, the distributor margin becomes a permanent cost you are choosing to pay. The route that catches people is the middle: a first order large enough to clear a factory minimum, from a brand that has not yet confirmed anyone wants the product. That is what the pilot tier in section 4.4 of the MOQ guide exists for.

The honest pitch

A negative verdict you can act on beats a positive one you cannot cite.

If your device is loud at the low setting, or the seal fails after ten washes, you need to know before your customers find out. Send the brief and we will tell you what the bench says — and we will tell you up front if we expect the answer to be negative.

Three lines every first brief gets wrong

How contract manufacturing runs →

A brief that cannot be quoted cannot be negotiated. The three places it usually fails, in the order they surface:

  • Engineering change notice — nobody writes one until something has already changed. State in the brief what counts as a change, who signs it, and what it costs, and the first disagreement becomes an invoice rather than an argument.
  • Component risk review — which single part, if it went missing, stops your line: the motor, the magnetic cell, the specific medical-grade connector. Single-source parts are a project risk before they are a supply risk, and the textbook treatment of supply chain risk management starts from exactly that mapping [Heizer, 2023].
  • Master carton, dimensional weight and batch code printing — carton count and shipping dimensions decide your freight bill before the device does, because carriers price the larger of weight or volume; and if the batch code cannot be printed legibly at the line, it will not be there when a retailer asks you to trace a unit. Packaging decisions sit downstream of logistics rather than beside it [Christopher, 2016].

Two books are worth owning before the first factory call: one on how a product specification becomes a manufacturable part [Ulrich, 2020], and one on why the supply network behind it behaves the way it does [Christopher, 2016]. Everything else on this page is a consequence of those two.
