$3.95
Today it costs $3.95 on AliExpress. Since Oct 26, 2026, when we started tracking it, it ranged from $3.95 to $4.74. It's the lowest price in 15 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 $5.27", but that is the store's own claim; we only state discounts our price history proves.
