"We have had a great experience with ADT. Responsive to our needs and monitor appropriately. Anytime equipment has needed to be replaced they have done so promptly and in a manner that is easy for us.
We have no worries about the safety of our home with ADT."

"I have had ADT for years and am very happy with the quick response they provide. My teenage daughters have set it off before and before they put in the code, ADT was calling to make sure we were okay.
I definitely feel safer knowing I have ADT. Thank you :)"

"I got the basic alarm that includes two keypads and a glass discriminator. The people during the installation were professional. They came and did what they said they were going to do. The service has been great and ADT is very competitive price-wise.
I had them since 2004 and I'm very happy with the service. Their customer service is excellent and they do everything they can to keep you as a customer which you don't see very much anymore."
