"I have had ADT for many years now. And I feel very secure with it. Use it daily. Many of relatives and friends asked about it. Told them how I would not want to go without it.
Hope some at least called ADT. When I am alone, I feel very comfortable and have no insecurities. Run out to get it now, you too will be happy you did."

"ADT is always there and has my back! Having the lifestyle I lead it just makes it easier to know someone is right there. Thank you ADT for always being friendly, delightful to speak with, and always a phone call away.
I have never had any problems with the service and am happy they watch over my home and my family."

"I am a new ADT customer and received an email with an amount due that I thought I had paid for with my installation. Tamara, the customer service rep was wonderful.
She was patient and took the time to go over every charge with me and to figure out if the total amount was due or not. She said, "I LOVE figuring these things out". She also made sure my charge card was updated and took care of processing the payment for me."
