The finding
Every record has an exact-model source and a dated offer receipt. Across the full catalogue, those records point to 229 distinct public URLs. That is a strong traceability base, but it is not the same as independent testing.
Owner feedback passed the exact-model and deduplication checks for 78 products. Each of those products currently has one usable pool, so the total is also 78 pools. A single retailer pool can reveal recurring owner concerns, but it cannot support a claim about buyers across the whole market.
Separate third-party evidence was found for only 9 models. Those records contain 18 exact-model sources in total. The independent performance-evidence flag is true for 10 models. This flag means an independent source passed the record's evidence rule. It does not mean Agent Review Data conducted the test.

Method and limits
- We used the validated production catalogue checked 27 Jul 2026, 22:04 BST.
- Distinct URLs include exact-model, offer, image, owner-pool and separate third-party source URLs. Repeated URLs count once.
- Owner-pool coverage counts only pools retained after exact-model matching and deduplication.
- The independent flag reports a passed evidence field in the product record. It is not a quality score and does not turn published claims into our own measurements.
- This is an audit of the catalogue, not a survey of every review or test available on the web.
