433MHZ Bezprzewodowy system alarmowy z czujnikiem drzwi przed kradzieżą z paskiem magnetycznym
arriver dans les temps
I guess you need to mention which frequency you want the item to be. its misleading that it supports both. I received for 433 and had to modify the receiver. but all working fine. 3 of them had low battery and replaced and all the items working fine as expected.
Buen producto.
