We show 22,206 products, one per title, in Automotive. At $77.69, it sits above the middle of that category, which is $15.49 — a range covering very different kinds of product, so read it as placing the price, not judging it.

The seller claims 43% off. Only 8,414 of the products we track claim a discount that large — 5.8% of the catalogue sits in the 40-49% band, so this one stands out. Either way AliExpress does not check strike-through prices, which is why we record our own instead of repeating theirs.

AliExpress reports 11 orders for it. For comparison, the median listing we track in Automotive reports 8 — though a category holds very different kinds of thing, so read that as scale rather than as a ranking. Order counts come from AliExpress and are not a claim about price.

We have recorded this product’s price on 3 separate days since 2026-10-10, and it has not moved once. This history was recorded over time, not reconstructed after the fact — the longer we track a listing, the stronger the evidence becomes.

If you buy through our link, AliExpress pays us 7.0% of the sale. It costs you nothing extra, and we publish the rate so you can judge our incentive for yourself.
