What our readings say: 1 of 7 reading-days recorded. We judge a seller's discount only after 7 separate days of our own readings.
Seller lists it at $39.98 — a claimed saving of $9.20. AliExpress does not verify that figure, and 23.2% of the listings we track make a claim in the same under 30% range, so on its own it means very little.

How this compares to everything else we track
We show 23,623 products, one per title, in Automotive. At $30.78, it sits above the middle of that category, which is $15.12 — a range covering very different kinds of product, so read it as placing the price, not judging it.
The seller claims 23% off. That is modest for this catalogue, where 35,038 products (23.2%) 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 6 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 1 separate day since 2026-11-14, 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.
