What our readings say: 3 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 29.77 CNY. The $4.49 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.

The price on AliExpress may have moved since our latest reading, 6 Nov. Purchase happens on AliExpress, under their terms — we never handle payment, and we earn a commission at no extra cost to you.

Seller lists it at $4.99 — a claimed saving of $0.50. AliExpress does not verify that figure, and 18.3% of the listings we track make a claim in the same under 30% range, so on its own it means very little.

How this compares to everything else we track

We show 10,854 products, one per title, in Electronics. At $4.49, it sits below the middle of that category, which is $6.04 — a range covering very different kinds of product, so read it as placing the price, not judging it.

The seller claims 10% off. That is modest for this catalogue, where 26,506 products (18.3%) sit in the same under 30% band and most of the rest claim far more. A small claim is at least a plausible one. Either way AliExpress does not check strike-through prices, which is why we record our own instead of repeating theirs.

AliExpress reports 104 orders for it. For comparison, the median listing we track in Electronics reports 116 — 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 3 separate days since 2026-10-23, and it has moved 2 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.
