[This review was collected as part of a promotion.] The C by GE wire-free smart motion sensor looks nice and functions as designed. But the app used to control it does not work correctly, crashes constantly, making the sensor useless. The app is supposed to tether the sensor to the light bulb but because the app is poor the sensor doesn't control the light bulb as it should. It's far too complex for what it is, If the app worked as it should it would be a decent product.

[This review was collected as part of a promotion.] The motion sensor does need to be mounted on the wall to detect motion, however I’d prefer an adhesive one instead. Also although it works it does in fact take a few moments to register any motion. I do like the fact you’re able to connect this with your phone which makes for easy managing.
