We track 16,677 products in Automotive. At $13.26, it sits below the middle of that category, which is $16.09 — a range covering very different kinds of product, so read it as placing the price, not judging it.

The seller claims 29% off. That is modest for this catalogue, where 14,436 products (13.3%) sit in the same under 30% band and most of the rest claim far more. A small claim is at least a plausible one. Either way AliExpress does not check strike-through prices, which is why we record our own instead of repeating theirs.

AliExpress reports 8 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 19 separate days since 2026-08-17, and it has moved 7 times in that window. 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.
