"The nice folks at simplisafe were very patient with me as I asked a lot of questions before getting a custom system. I couldn't be happier with it. It was very easy to install - the instructions are amazingly clear - and they have thought through every detail. It's difficult to express just how good it makes me feel to hear that "alarm on" when I come home at night after a long day at work. Thank you!"
