Title: Great unit - short range
Review: This has already saved me a few open-garage nights. The simple device blinks a red light when the garage is open and has a solid green light when it's closed.I gave it 4-stars due to it's range. When I first installed it, I placed it behind a metal brace to hide and protect it. I wasn't able to receive a signal consistently from the other side of the wall from the garage. I moved it out into the open and haven't had a problem since. Overall it's a great unit but it doesn't work much past 30-40ft.
