How this compares to everything else we track
We show 13,496 products, one per title, in Sports & Outdoors. At $8.16, it sits above the middle of that category, which is $6.71 — a range covering very different kinds of product, so read it as placing the price, not judging it.
AliExpress reports 23 orders for it. For comparison, the median listing we track in Sports & Outdoors reports 104 — 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 2026-11-02, 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.
