TRACKING · DAY 5/7Sports & Outdoors
What our readings say: 5 of 7 days recorded. We judge a seller's discount only after 7 separate days of our own readings.
AliExpress prices this listing at 143.65 CNY. The $21.57 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 $43.15 — a claimed saving of $21.58. AliExpress does not verify that figure, and 37.2% of the listings we track make a claim in the same 50-59% range, so on its own it means very little.

We track 8,169 products in Sports & Outdoors. At $21.57, it sits above the middle of that category, which is $6.48 — a range covering very different kinds of product, so read it as placing the price, not judging it.
The seller claims 50% off. So do 30,359 other products we track — 37.2% 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 108 orders for it. For comparison, the median listing we track in Sports & Outdoors reports 135 — 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 10 separate days since 2026-09-12, and it has moved 4 times 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.
