What our readings say: 6 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 26.42 CNY. The $3.99 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 $8.99 — a claimed saving of $5.00. AliExpress does not verify that figure, and 36.6% of the listings we track make a claim in the same 50-59% range, so on its own it means very little.

How this compares to everything else we track
We show 5,277 products, one per title, in Computer & Office. At $3.99, it sits below the middle of that category, which is $7.42 — a range covering very different kinds of product, so read it as placing the price, not judging it.
The seller claims 56% off. So do 55,151 other products we track — 36.6% 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 1,198 orders for it. For comparison, the median listing we track in Computer & Office reports 85 — 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 6 separate days since 2026-09-23, 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.
