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.
AliExpress prices this listing at 23.17 CNY. The $3.49 above is that figure converted by their affiliate API. AliExpress’s own site converts at a slightly different rate, so it may show a few percent less — the CNY number is the one neither of us converted.
Seller lists it at $10.28 — a claimed saving of $6.79. AliExpress does not verify that figure, and 14.9% 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 22,852 products, one per title, in Automotive. At $3.49, it sits below the middle of that category, which is $15.31 — a range covering very different kinds of product, so read it as placing the price, not judging it.
The seller claims 66% off. Only 22,056 of the products we track claim a discount that large — 14.9% 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 4,532 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.
2 shops we track list this same product, between $3.49 and $4.45. Same title, same photos, different seller — AliExpress does not group them, so the price you see depends on which listing you happened to open.
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.
