    "Love it...V cool....I think this is a great product it does exactly what it says it's going to do plus some, we are using it as a training tool for a pet so basically whenever the padlocks into a certain area we make the lights do a really funky little dance and therefore we can catch him in the act and it's working....The customizing part of the sensor is pretty nifty as well, where you can put it at super sensitive, so mid day, your dog or cat isn't going to walk into the room and turn on the lights, or you can make it super sensitive where a window shade moving in the wind can set them off."

    "Love it...Nice Add...I was hoping the app would let you use multiple sensors at once but you can only use a single sensor at a time to base your thermostat temperature so I would have been fine with just a single remote sensor....The Nest temperature sensor does exactly what it's supposed to do: gives me a remote sensor I can put far away from my thermostat so I can keep distant parts of the house comfortable."
