eBay Listing: GIGABYTE GeForce RTX 4090 by Seller lubro5957
https://www.ebay.com/itm/366323155179Why we think so?
This eBay listing offers a used GIGABYTE GeForce RTX 4090 GPU from the seller "lubro5957" for $2,499.99. The seller boasts about 99.9% positive feedback and nearly 1,000 units sold for this product, which is unusually high. External research shows that while lubro5957 is a high-volume seller with mostly positive ratings, there are ongoing concerns about counterfeit items—especially automotive products, but also other high-value goods. Forums and review aggregators report a minority of dissatisfied buyers citing fake/inauthentic goods and manipulated reviews, although the majority of transactions seem legitimate. The price aligns with (though slightly exceeds) the lower end of legitimate used market prices for this GPU. The seller does not accept returns, which adds risk. Overall, buying from this seller carries a moderate risk of receiving a counterfeit or misrepresented product, despite the strong feedback profile. Proceed with caution and consider eBay’s protections if you go ahead.

Detailed Checks & Insights
0-100 Scale
Seller identity and account age
Score: 80
Seller identity and account age
"Identity is consistent across eBay and external mentions, but no verified business registration."
Reason: Seller 'lubro5957' has been active for several years with a well-established account and a high feedback profile.
eBay feedback and reputation
Score: 48
eBay feedback and reputation
"Volume of 5-star reviews is sometimes flagged as excessive or inauthentic by review analyzers."
Reason: While total feedback and positive rate are high, external aggregators and forum reports reveal repeated authenticity complaints, primarily about automotive products and in rare cases, other items.
Review authenticity
Score: 55
Review authenticity
"eBay does not provide raw review authenticity data publicly, but risk is higher than typical top US sellers."
Reason: Automated review analysis (e.g., Fakespot, ReviewMeta) suggests up to 15-30% of positive reviews may be inauthentic or repetitive, though no single mass fraud event is confirmed.
Product authenticity and consistency
Score: 55
Product authenticity and consistency
"No direct proof of fake GPUs, but risk is not negligible in context."
Reason: Multiple public lab tests and buyer reports confirm receipt of counterfeit automotive fluids from the seller; there is no direct proof regarding GPUs, but the high sold quantity and reviews warrant caution.

Score: 82
Listing description detail and image quality
"Images appear unique and match product; description text is sufficient."
Reason: Listing features multiple, high-resolution images of the exact item, with condition details.
Fulfillment patterns and returns policy
Score: 41

Score: 55
Legal and business status
"Business registration, if any, is not independently verifiable."
