We show 22,852 products, one per title, in Automotive. At $16.37, it sits above the middle of that category, which is $15.32 — a range covering very different kinds of product, so read it as placing the price, not judging it.

The seller claims 58% off. So do 51,779 other products we track — 35% of our whole catalogue claims a discount in the 50-59% band. At that frequency the figure is a listing convention rather than a signal. Either way AliExpress does not check strike-through prices, which is why we record our own instead of repeating theirs.

AliExpress reports 9 orders for it. For comparison, the median listing we track in Automotive reports 7 — 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 1 separate day since 2026-11-11, 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.
