Quick answer
Is $3.79 a good price for Lanrui K7S Inductance Detector Type-C Powered for Phone Motherboard…?
It is the usual price, not a deal: $3.79 is in line with the typical price of $3.95 that DipScout measured over the last 14 days. It is the lowest in 20 days, but it has held this price since Nov 7, 2026.
$3.79
Today it costs $3.79 on AliExpress. Since Oct 23, 2026, when we started tracking it, it ranged from $3.79 to $4.15. It's the lowest price in 20 days, but it has been at this value since Nov 7, 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 $7.89", but that is the store's own claim; we only state discounts our price history proves.
