"I would like to recognize employee Doug A at SafeStreet/ADT. We’ve had an old security system sitting in our house for over 15 years without service or functionality. He took the time to explain the differences between how the old systems work and how the new systems work. He was patient with us, and we are happy customers."

"ADT is the best company to talk to in terms of security alarm. Being a locksmith myself I know how important it is to deal with the right people. I referred a lot of customers to them and so far they are happy with their service. I myself got one for my house. Thank you for a consistent service and great deal."

"Dan did an outstanding job addressing our needs with our new home we purchased recently. He keyed several doors and made all the locks match so we can use the same key for all of them. Dan was friendly and very responsive and completed the work efficiently. We won't hesitate to use him again!"

"I really don't like that much, but it's okay. I just think that the contract is too long for what they offer. All of their equipment is falling off the wall, it's like you install it yourself. Then I get an alarm on the garage door that says it is closed. It was open and had a delay on it. It's like sometimes they have to return to make sure that it closed because they figure the garage door was left open, but I did close it before I left. Several minutes later they come back saying it was closed. and then I got a message saying my garage door was left open."
