Is $3.99 a good price for 12V 24V 110V 220V 230V External 2CH Universal 433mhz Garage Door…?
It is the usual price, not a deal: $3.99 is in line with the typical price of $4.04 that DipScout measured over the last 14 days. It is the lowest in 17 days, but it has held this price since Nov 5, 2026.
$3.99
Today it costs $3.99 on AliExpress. Since Oct 23, 2026, when we started tracking it, it ranged from $3.99 to $4.34. It's the lowest price in 17 days, but it has been at this value since Nov 5, 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 $4.39", but that is the store's own claim; we only state discounts our price history proves.
