This electronic Hand Light Switch is very useful in the rooms where the initial light switch is situated far from the entrance. And thus, you need to walk through the dark room first running into risk of stumbling upon something. The device can be adjusted to respond to either sound or movement. If you choose the former, you can adjust the volume of the sound as well the general noise levels in the room.
As a result, it will not go on and off as a crazy Christmas light when you start talking. The device comes in white color, which would certainly match any room. The device is also very minimalistic (9*9*5cm) which makes it nearly invisible, so that you can be sure that usefulness does not interfere with beauty.
