I thought seriously about giving Vivint two stars,...

I thought seriously about giving Vivint two stars, but finally gave in with a 3. I have a variety of issues with Vivint. The first is with tech support. We seemed to have finally gotten the most serious issue solved, the motion sensing camera. We originally were set up with an older style camera. That camera couldn't keep the internet connection for more than a week. Usually, I could get it reconnected. When I couldn't it meant a call to tech support. I had to go thru all their steps to try an get an appointment with a tech set up. That's where problems usually came up. Many times the appointment was a month or more away. So part of my system wasn't working for an extended period of time. They replace the camera several times, added a dedicated router to my internet, but nothing worked. At one point, our local Vivint was having lots of issues and had techs in from outside our area. We got an outside tech and she got our camera problem fixed by going to a different style camera.
Another issue that we have had is one many people have mentioned, Vivent's different battery powered items eat thru batteries like crazy.
The last issue I have is with the cost. For what you get, this system is on the upper end of the cost spectrum. For what we pay Vivint, you should have, at least, the same week tech support and a better system.
Not only would I not recommend a Vivint system, I'm looking at other systems for when our contract ends.
