Today it costs $4.22 on AliExpress. Since Oct 27, 2026, when we started tracking it, it ranged from $4.15 to $4.25. It's the lowest price in 7 days, but it has been at this value since Nov 6, 2026; by our price history that is already the normal price, not a sale.
No drop compared with what we observed over the last 13 days. The store advertises "was $7.82", but that is the store's own claim; we only state discounts our price history proves.
