Lousy! I have been using ADT out of Morrisville and they are lousy when it comes to post sales support. Currently, I have a system issue that they have yet to address after two months. They have not shown for scheduled appts, wanted to reschedule appts, and now, they say they can't do what they said they could do with respect to failover from landline to wireless. ADT, you need to get your act together. Maybe CPI will do better?
