Today it costs $20.99 on AliExpress. Since Oct 29, 2026, when we started tracking it, it ranged from $20.99 to $23.39. It's the lowest price in 14 days, but it has been at this value since Nov 4, 2026; by our price history that is already the normal price, not a sale. Price checked on Nov 13, 2026, 18:22 UTC.
No drop compared with what we observed over the last 14 days. The store advertises "was $26.57", but that is the store's own claim; we only state discounts our price history proves.
