Manufacturer Claims vs Evidence: A Field Guide to Marketing Language
This site's standing rule: every claim is labelled by its evidence layer — manufacturer claim, retailer table, or owner report — and never silently promoted to fact. Use the same discipline when you read any listing, including ours.
Claim-by-claim
| Claim you will see | Evidence status in our research |
|---|---|
| 'Medical-grade' / 'food-grade' silicone | Observed on retailer pages for multiple brands; no certificate, standard number or test body found on any recorded page. unsupported marketing language — not thereby proven false, but entitled to zero weight until a certificate appears. |
| Lifespan years ('lasts 10+ years') | Mutually inconsistent ranges across guides for the same materials. A range-of-claims, never a fact. |
| 'Permanent makeup' | The retailer's own FAQ concedes the coating lightens/thins with rubbing over time. Read as longer-lasting. |
| Body painting durability | Retailer care text: ~a year for display/photo use, potentially days under friction-heavy use (reported). |
| 'AI learns and gets smarter the more you talk' | A product-page claim with no independent test in any source we found. unknown. See Emerging technology and limitations. |
| Struck-through 'MSRP' discounts | Do not represent a real market price; sale prices across dealers roughly agree once currency is considered in the Gynoid case examined. Compare configured street prices only. |
| 'Free' bundled features | Rotate monthly at some brands — free in one retailer's promo, +$99/+$150 à la carte at another for the same features. Date-stamp every 'free'. |
| Weight-reduction claims | Real engineering, inconsistently based — same body spanning ~6 kg by basis. Verify basis, not the headline. |
The three questions that deflate most claims
- 'Shown where — certificate, standard, or test?' 2. 'Measured how, on which version, with what included?' 3. 'Who else, independent of the seller, reports this?' If a page — again, including ours — cannot answer for a claim, discount the claim, not just the page. Our comparison method is set out in How to compare quality and applied in ZELEX vs Starpery.
