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

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
