Good quality, good price, and great function! Multi-purpose is the key. Is the door/window open or closed, whats the temperature, whats the level of charge on the battery, is the sensor perpendicular or horizontal, is there vibration? Use your imagination. This switch can be used in so many ways.

The sensor works great it has a good detection range and built-in magnet for easy mounting. The only thing to watch is the battery as after a 30% reduction it might actually go to 0%. The reporting could be better.
