Bought 2 locks, they never worked kept getting disconnected finally after several replacements they agreed to sending me a return label for refund. That was months ago and now I can't even reach corporate. My next complaint will be with FCC and small claims filing - the worst customer service in the world. The product is equally poorly designed with way too many quirks that cannot be resolved because of the crappy service! Do yourself a favor buy anything else dont be the person that has to hear 'told ya'.
