Very easy installation. Solved the problem of an annoying buzz from the old one. Would purchase again.

I got the 1321 and it made installation of my Vista 20P panel incredibly easy. This and the Tuxedo Touch were the most awesome products I bought in addition to my panel. I am loving these things.
