"When I call ADT with a question, the representative is very knowledgeable and pleasant. The ADT Pulse app is easy to use and when I just go out to walk the dog...
I am confident that my house is secure.

"I’ve had ADT for over 20 years. One gentleman did the installation for a few hours and he did a great job. He updated stuff and it went really well.
They're a good company and they do their job."

"We had been an ADT customer for years before moving and make the huge mistake of going with the Xfinity package including home security.
We quickly switched back to ADT since they are truly the best in the home security business -- from sales, installation staff, phone support, technical help... and most importantly monitoring our home effectively. If we ever move again, we will always choose ADT."
