    Junk from china. This only works intermittently so you can not depend on it. Waste of money.
    HOWARD -- henderson, NV   10/5/2013
    works perfect. I always know if I have forgotten to close the garage door.
    KENNETH -- capistrano beach, CA   4/8/2012
    Don't bother with this item. It is not a stand alone unit. It requires a receiver too. After paying shipping charges both to receive and return I was out about$12!
    CHARLES -- new city, NY   1/29/2012
    It works really well. Its mounted about 50 feet from receiver and has no problem with reception. Used supplied screws to install - quick and painless install.
