Vivint has impeccably and I would recommend them to family and friends.
Vivint's installation and customer service was Great! I would recommend them to anyone!
The service is fine and they do their job. However the door lock will not lock from the app or the keypad, only manually from the inside. When I asked customer service for help they basically gave me instructions to take the whole thing apart and re-install it. I am not a tech and I pay for a service that works...
