I was bought a contract with Vivint through a very pushy salesperson in my home in 2012. I had company at the time and he was rude. I was told the contract was for 2 years - I have since called the company and told that it was 6 years - I could not find the above referenced NOC letter on their site. I can tell you that I NEVER signed up for 6 years and feel that it was a bait and switch.
I no longer live in a house with the equipment. and have never had to use it.
When it was reinstalled in the new house the tech put the box
in the back hallway and not in the bedroom or near the door so it was never used.
Reason of review: misstateed length of contract.
Vivint Cons: Pushy door to door salesman.
