The installer was amazing. The sales person was amazing even threw dealing with some issues not seen. My only complaint is that I am paying more to have the ability to access my alarm threw their moble app. However I have yet been able to figure out how this works. Customer service called and instead of just telling me go to the App Store or let me tell you how I was questioned about if emails were sent giving me directions....... If I had gotten them I wouldn't need your help??????
