Vivint has impeccably and I would recommend them to family and friends.
So far I have been waiting since mid May to have one of my sensors moved, because the location that it's in is near a window and was setting off false alarms. Well needless to say, it's nearly the end of June and it hasn't been fixed, because apparently the techs can't locate my house, but we're able to locate my house to sale and install. They have cancelled twice and once without notice. So when they called this time to cancel, I got aggravated. I told them to either send someone at the scheduled time or the next available appointment they have they can come to install it. So we will see what happens next.
I like the WiFi capabilities.
