This was a very easy add on. Open the box, pulled the tab, stuck to the door and it was good to go.

So we bought whole system of Simply safe and it is to install, no wires, no screws

SimpliSafe is quality and reliable. This was a backup unit on out building and works just like the original. Very happy.
