Such a fast delivery did not expect. Came together with the second order for 19 days from the date of order. The seller is good. everything works

L**n 10/05/2021

All the leds on the board unexpectedly turned out to be red. Replaced the pow led with a more familiar green, at the same time and a resistor to the led by 10 k. As a result, the simple action of consumption current decreased by 25%. I recommend!

S**y 05/10/2020

Very powerful buzzer, makes quite high noises, very good buy very cheap and very good
