Complaint Review: Vivint

I've had the Vivint Sky system now for two years and have continued problems with it.  What was sold was not able to be delivered.  Problems include cameras that don't stay on-line, thermostats the go through batteries every month, door locks that go through batteriers, changing features (mostly removing features - like Weather Channel display on panel is now gone, setting to disarm system when unlocking at door is no longer available, and others), and continuous problems with the website for remote access (can't see cameras, unsupported browsers, no smartphone access).
