What our readings say: 4 of the 7 reading-days a verdict needs, and none in the last 7 days.
Seller lists it at $270.97 — a claimed saving of $184.26. AliExpress does not verify that figure, and 13.8% of the listings we track make a claim in the same 60-69% range, so on its own it means very little.

How this compares to everything else we track
We show 22,366 products, one per title, in Automotive. At $86.71, it sits above the middle of that category, which is $15.43 — a range covering very different kinds of product, so read it as placing the price, not judging it.
The seller claims 68% off. Only 20,205 of the products we track claim a discount that large — 13.8% of the catalogue sits in the 60-69% 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 55 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 4 separate days since 2026-09-23, 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.
