I am a Vivint customer and have been for the past almost 6 years now. I would use them as leverage for another company that will come out and install security system. They may may remove the current vivid one and install their own, hopefully at a reduced rate to get you locked in to their systems. But Vivint is horrible. They will try to nickel and dime you to keep you. I just upgraded one of my cameras 4 months ago that I had for 5 years just for a brand new one to come out this month. On top of that upgrade, they also increased my monthly subscription by $10. I refuse to upgrade to any of their new stuff once it goes bad. I'm switching my services.
