We've had The Monitoring Center for about 9 months, prior to that we had another security company that was 3x the price. TMC is awesome, we accidentally set our alarm off the other morning, it took me about 5 seconds to put in the code and turn it off. Two seconds later the phone rings and it's TMC calling to check on us. Our old alarm co never called when the alarm went off, they were a joke. We are super happy with The Monitoring Centers' service.
