Walked for a long time (29 days to Voronezh), brought Courier sdek, in appearance quality, work confidently, when the voltage on the battery is less than 5 V, the LED blinks once every three seconds (according to documentation like and the signal should send, but not yet found), the signal is good, took 6 PCs for the bundle domoticz + rflink, It was difficult to start and while working with variable success (the signal of opening, closing and dismantling from different devices, had to add a virtual device and write a script, but this is not all, periodically close and open signals are sent from several devices and you need to add and configure them all (To one sensor tied three devices for opening and three for closing and it works stably)) in general, in such a bunch you can use, but not without crutches and without bubn

Bought an additional sensor for its not very new alarm, Kerui 6120G. The sensor has no problem connected to the main alarm unit and works fine. There were no failures in the work yet. The product description corresponds.
