"After my husband died, I used the Stay feature at night and even during the day. ADT responds immediately to any alarm, even when set off by mistake. They call all the numbers on the list I have given them to verify if there is an emergency.
Their customer service people have helped me establish secondary codes for visitors. I would recommend ADT to anyone, and often do."

"We had ADT before we had Comcast. While with Comcast, we found out that it was divided into two sections, selling it and the actual security. It wasn’t very responsive so we switched back to ADT. Tyler, the sales rep, was always pretty responsive and their installer was great too. I'm satisfied with my service and it seems to be working really well.
The only thing was I bypassed three zones, and originally, the technician that installed it put a shortcut into it, but I forgot what the shortcut was. When I called back, they said I had to call out the technician again to put that back in and they would charge me for it. I wasn’t too pleased with that. But other than that, ADT works really well."

"ADT has been wonderful and they are very responsive. We've had them for many years. We have a yard sign and a monitor control box at the basement entrance and in the living room. Also, the representatives are very good, nice, pleasant, and informative.
One time, they called me and I followed up down in the lower monitor box and I got a call right away. They wanted to know if everything was all right and they fixed it right away. It was nice of them to call."
