I wouldn't buy this thing again. We have it running a lamp next to the front door. There's no wall switch for that outlet, and the switch on the lamp is a bit cumbersome, so I thought the clapper would be a convenient way to turn on the light when returning home at night. It is, but the unit is way too sensitive. Maybe it's the acoustics of the room (hardwood floors), but just about anything will set it off. Ours has the adjustable sensitivity and even with it set fully to "home" mode (least sensitive) it gets triggered when not desired. It will eventually get scrapped when we get a different lamp with a more accessible switch, although I'm just about fed up enough to do away with it even before then.
