I should have read this review before I got with ADT. I have been with ADT for three months now. The other day someone broke in my home meanwhile I was asleep. I called asking why it didn't go off and their response was: WELL, WE ONLY PUT FOUR SENSOR AND THAT WAS FOR YOUR DOORS. BUT IF YOU LIKE YOU CAN PURCHASE SENSOR FOR YOUR WINDOW. The key pad I have it's for people who have doors and window sensor and I was told that it would be secure. When I had called to cancel they said I had to pay 75% of my three year contract. I had told them I read the guarantee for six months if not satisfied. The response was WELL, WE APOLOGIZE AGAIN.
This is their money guarantee: http://www.adt.com/wps/wcm/connect/a479d10041359c47836583c0ef0abfd6/L7232-04-ADT-GuaranteeCert4up.pdf?MOD=AJPERES
ADT IS NOT ALWAYS THERE.
