We show 22,413 products, one per title, in Automotive. At $19.64, it sits above the middle of that category, which is $15.44 — a range covering very different kinds of product, so read it as placing the price, not judging it.

The seller claims 33% off. Only 5,620 of the products we track claim a discount that large — 3.8% of the catalogue sits in the 30-39% 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 4 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 2 separate days since 2026-10-12, and it has moved 1 time 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.
