NOT READ RECENTLYElectronics
What our readings say: Our newest reading is over 4 days old. Across 14 readings it ranged $16.74–$20.08.
AliExpress prices this listing at 133.79 CNY. The $20.08 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 $40.98 — a claimed saving of $20.90. AliExpress does not verify that figure, and 37.6% of the listings we track make a claim in the same 50-59% range, so on its own it means very little.

Seller on AliExpress
We have 14 readings of this listing’s price since 13 August 2026, from $16.74 to $20.08. Full specifications are on the AliExpress product page.
4 products in Electronics close enough to compare on price — 4 are cheaper than this one.
We show 9,595 products, one per title, in Electronics. At $20.08, it sits above the middle of that category, which is $6.09 — a range covering very different kinds of product, so read it as placing the price, not judging it.
The seller claims 51% off. So do 48,441 other products we track — 37.6% 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 110 orders for it. For comparison, the median listing we track in Electronics reports 114 — 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 14 separate days since 2026-08-13, and it has moved 11 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.
All between $10.04 and $20.08, with at least 100 reported orders.
