Today it costs $5.77 on AliExpress. Since Oct 22, 2026, when we started tracking it, it ranged from $5.77 to $6.28. It's the lowest price in 22 days, but it has been at this value since Nov 2, 2026; by our price history that is already the normal price, not a sale.
No drop compared with what we observed over the last 14 days. The store advertises "was $6.28", but that is the store's own claim; we only state discounts our price history proves.
