Vivint did a great job coming in and signing me up to a 3 year contract....unfortunately during the install they stole from my house (they removed a yard sign and replaced it with theirs) and did a poor job at installation. For the first 6 months they forgot to bill me dispite having my credit card info and now my system works sporadically and is glitchy. This is my first experience with security. My advice is to be careful out there.
