Very good gadget if you don't have a switch somewhere you want it. I permanently placed it above my bed, as I didn't have a switch for the light in that spot. So far, it works perfectly.

Very useful. I installed it in a light fixture where the switch was in an inaccessible spot due to the old house (on a shelf in an open bookcase). Except for the fact that I had to use a socket adapter because its shape is a bit strange, it is very convenient to be able to turn on/off the light from wherever you are. I would like a slightly better build quality, but for its price, it's unbeatable...
