"I like having ADT. My experiences with them have been mostly positive. When one of my wires was loose, a nice gentleman came by and repaired that.
He called me ahead of time before he came and cleaned up after himself when he was finished with the job. I would recommend ADT because I’ve had success with it so far."

"I'm 82 years old and when my husband passed away in September, my children told me that they wanted to get me an alarm security for a Christmas present to make them feel more secure that I was alright.
My house has been broken into three different times where all my guns and antique clocks were stolen. I also work at Walmart from 1:00 to 10:00 at night and my kids said that they didn't want me coming home at night and not feeling like I was secure at the house.
They got me an alarm system with ADT and when it was installed, the tech was a very nice person. I feel safe and very secure having them, and so far, I'm very well pleased with their service. I also feel that when I come home, pull in the driveway, and into the garage, there would be no one that had broken in to the house and be waiting for me to come home like I hear on the news. I appreciate ADT and I couldn't find a better company. I would highly recommend them to anyone. As a matter of fact, my neighbor over here on the corner stopped by to ask me about my security system and I told her about what my experience with ADT. She said she was going to call them and have them install one for her, and she did."

"Having ADT Security makes me feel safer while I'm in and away from home. The system is easy for me to use and I can check in on my home at any time and actually see what's going on.
I find the system very reassuring."
