Very good
Very easy to install, good price, the only problem is the magnet and sensor need to be install very close together

Works well
This works well on most door types, we have a UPVC front and back door, UPVC french doors, wooden internal doors and a shed door with these fitted. We have also installed then in a few of the ground floor UPVC windows. The range is not great for the shed, but it does just about reach.

Failed out the box
One of these came with the bundle I bought. Doesn’t work whatsoever, keeps saying the sensor has failed over and over and no way to fix / reset the device. Garbage, would expect this kind of tech from an unnamed Chinese company. Not even cheap at £25 a sensor, don’t waste your time.
