Love IT!!
First time installing a garage door opener. There were a few tricks or things that seemed in reverse order in the directions. Thinking the deadbolt was "added" security I wasn't planning to us it, but then realized because this lifts the tension cables there is no pressure on the door when its down so in theory someone could open the door about a foot before the cables got tight again.
Installed and operation; i'm very impressed. It's quiet, almost to the point you forget it's opening. The loudest sound is when the auto deadbolt opens with a click, after that it's quieter then if I opened the door manually. The remote lights up when you wave your hand in front of it. The light can be placed anywhere in the room and it turns on when the door opens :). The keypad has a motion sensor that can be set to turn on the light when there is motion in the garage. Very happy with this product.
