"Feel safer with ADT. If I accidentally set off alarm, the phone rings promptly checking to see if everything is okay. So glad to have the alarm system.
I know if there ever is an emergency situation, ADT is there to assist me."

"We are very satisfied with ADT and its customer service. We have been loyal to ADT and will continue to do so. Highly recommended. Yes, we would recommend ADT to our friends. We have several false alarm incidents because my son(s) have autism.
ADT customer service is very understanding, helpful and reliable. We will continue to do business with ADT. We don't have any complaints with ADT, thus far. Thank you, ADT!"

"The person was very professional, fast and friendly. I would highly recommend ADT for a security firm. The system makes my wife and I feel more secure while we are home or away.
We have been long time customers and do not plan on changing anytime soon."
