Puck reach is a joke. You have to have it so close to what you want to control that it's difficult to control more than one device. This assumes you can manage more than one device. I have a very common brand DVD player and the puck couldn't get away. I concede that he had excellent control over my TV. So 1/3 of the devices get 2 stars. I can't say I would recommend this item to anyone.
