Most small GPS trackers aren't really GPS they utilise wifi and bluetooth to be found by your phone. This small but powerful device tracks your location wherever you are, great to place in a suitcase and track it if it gets stolen.
It is pretty hard to find that light switch in the dark especially when it is in your closet. The OxyLED light is a great product that turns on when it detects motion! Yeah it is better than the clapper.
