Works very good. Rarely have to readjust, etc.

Have this installed on my garage door which goes straight up and down. Works perfect, only issues is when it's -neg degrees outside, but that's to be expected when the battery has nothing between it and the great outdoors but thin metal. Remember this ge smart choice system has a very short range. Don't expect this thing to go through lots of walls, etc. even with an extender. It's a cheap alarm system for small areas.
