Comparable products we track

8 products in Electronics close enough to compare on price3 are cheaper than this one.

How this compares to everything else we track

We track 6,416 products in Electronics. At $2.25, it sits below the middle of that category, which is $6.26 — a range covering very different kinds of product, so read it as placing the price, not judging it.

AliExpress reports 1,224 orders for it. For comparison, the median listing we track in Electronics reports 125 — 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 15 separate days since 2026-08-23, and it has moved 7 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.
