We have had a contract with Safe Guard for only a year now and have had 7 service calls for faulty wireless connections (which of course not their fault, we need to learn "to get over it and let them keep fixing it and we need to believe in their company" which was what I was told by one of the "Customer service" reps).
Seriously, I was told to get over it and when my Valentines Day was ruined the guy had the balls to tell me that if I was his wife, he would tell her to cancel the service, but since I wasn't, I should get over it. Don't believe it when they say wireless... it really means "magnets that will fail on a dime". Their excuses were, and I quote "it is the humidity in the air, it is the moisture in the air, it is environmental, and my ultimate favorite was, maybe it is your son. My son is 2 1/2 and cant even get to his window. And the alarm goes off when we AREN'T at home so lets blame the kid. DON'T SIGN A CONTRACT... If they give you free service for all of your problems, then you still have to pay up to 30 months of UNPAID months to get out of your contract. We only paid 3 months and they consider the other 10 months as unpaid.
Run, not walk, away from this company!!!
