I have to say I was surprised by all the negative reviews of ADT service. I have been with the company for about 6 years, 5 years at our prior home, and 5 years at our home before that, and have always had very good service. Our system was already installed when we moved in and we had it upgraded a year later with additional door sensors to cover every possible opening. It actually works too well sometimes because we have accidentally tripped it a number of times.
