My wife doesnt typically answer the door unless she is expecting someone but she did when Envision sales reps showed up. We let them give us their pitch and it actually didnt sound bad. I was in the market for a security system anyway so I was interested in hearing more. I let them in and they won me over with their research, technology and support. I was able to sign up for a couple of can goods.The installation date was miscommunicated within their system and they rectified it immediately and even gave me one month free for my inconvenience. The technology is top of the line and it has been working great since install. I love the fact that I have a local company in Envision and a nationally backed security system in National Security Systems. Ill definitely recommend to my neighbors and friends.
