"Better be safe than sorry! Couple weeks ago we realized that we were pressing our luck by not having any type of alarm or security automation system. Used Alarm Protection Group to get a standard system that sends us alerts if the doors open and we can turn lights on from our phones when we aren’t home."

"Very old alarm security system was in our house from the prior owners. It wasn’t hooked up to any monitoring or power. Max came out from the ADT Premier Provider group and got us modernized for sure. Everything is now wireless and we feel good about our choice to go with them."

"Good price. Typical monitoring services. My only real issue is that most of their account servicing needs to be done via snail mail or over the phone--they do not have a website to update contact info, billing info, or other details."

"Install was easy. Up front cost was pretty low with Angie's List coupon. Monthly price is a little high compared to competing companies. Response time with alarms is excellent. I was advised to use glass break alarms within 10 ft of my first floor windows, which we installed correctly. I asked prior to installation if having one in the kitchen would cause false alarms due to dishes clanging, etc. I was told the glass break alarms are configured to a precise frequency that alarms with breaking glass. So, not a "no", but not really an answer. Well, every time we cook dinner, wash dishes or empty the dish washer, the kitchen glass break alarm gives a warning which would sound the alarm if it was set. This has caused us a number of false alarms while we've been away due to shifting bowls or plates in our drying rack. For the first several we've had to pay our police department $120 to check the house, and I was only notified after the first alarm that there was a cheaper option for a security company to drive by to check for a break in."

"We learned on a Friday afternoon that my husband needed a criminal background check in order to participate in an international program - that he was scheduled to fly out for on Sunday morning! We found many online providers that offered an "instant background check" service, but were hesitant to give his SS# to just anyone, so we came to Angie's List to see if any trusted providers were listed here. Upon finding CSI Secure Solutions, I called them directly, and Chris himself (the owner) answered the phone. He personally committed to get it done, and he worked with me directly to get exactly what I needed within the time frame required. He made a stressful situation very seamless and simple, and I recommend him extremely highly!"

"I spent $400 on that work and I thought that it. They used a product which sort of like liquid wood and they applied it to the area that was dug out and painted over it when it was dry. I liked that he just worked right away and did not stop to talk. He did not take a lot of breaks or smoke and I thought that he had excellent professional skills and work ethic."
