Other Thoughts:I got this item a while back to plug in lamps for my house so i no longer have to walk across a dark room and man can i say its the best investment now i am gonna get more on the same channel so i can turn on a lot of things at once with one control
Other Thoughts:This is exactly what we needed, we are using it under our deck for our pond pump. Can turn the pump on and off anywhere from the house. I wish it came with 2 remotes but it works fine as is.
