"I wanted to get a security system but had no clue where to start. I went ahead and used Angie's List as a reference. We’re happy with our experience dealing with Alarm Protection Group. Bought their starter package that covers our doors, windows, 3 motion detectors, and a sleek control panel."

"Our dealings with Protect Your Home/ADT were delightful. We received a call back very fast after requesting a quote through Angie's List. We were able to complete everything on the phone; there was no paperwork or downtime. I had to call Customer Service with a question about the keypad, and they ended up telling me other helpful details on top of my original question."

"The job was good and there were no problems. I originally wanted new keys made for my exisiting lock but was told that they could not do that. So a new lock was isntalled instead. Although the work was good and the locksmith was courteous and professional, I just did not expect to pay that much to replace a lock.
