I have been a Deluxe Alarms customer for more than 5 years. Generally satisfied with the services provided. The monthly costs are reasonable. When I need to call the monitoring centre, they are always easy to get through to and very helpful. Recently I had to change my battery, and I was pleasantly surprised that the new battery is included with my plan. They have long working hours, which made it very easy to go to pickup my new battery even after a long work day. The employee at the Concord location was very helpful and answered all the questions I had for him. I will definitely recommend this alarm company.
