Works great. Very good manual in english. if set to 10m or 8m setting detects moving objects through walls. there are settings for 2, 5, 8, 10 m. 5m works best for my application. 2m setting is too low on sensitivity. more like 1.5m. The bad thing is it does not fit East European style boxes for electrical circuits. You can not cut the corners on the back to make it fit in the recessed circuit box cause the rectangular shape on the back follows the logic board. For Eastern Europe and Russia this will not fit round recessed electrical circuit boxes.
Everything OK
