I've had ADT for about 4 years. Never had any issues . . . even with Comcast Digital Voice. And yes, it's been tested! My issue was that they kept raising the price which was NOT justified. Costs aren't going up and I'm not getting any better equipment. In case anyone is curious, your contract probably does allow termination on price increases (mine did)-- although they did offer to waive the price increases once I told them I had signed up with someone else because I had had enough of their increases!!
ADT's installation billing is a scam. I had a previous alarm and ADT took over the monitoring and used much of the equipment. They charged me for an outside sounder, but never installed on because my old one worked fine. Technician said it wouldn't be a problem - just call for a refund on that pieco of equipment. Not a problem - what a joke! $ seperate calls over two months providing every detail of information, the only responses ADT gives are that they are "looking into it" and that a credit had been submitted, but it takes a month to "process" - what rubbish! They could simply credit my credit card that day. To all who are shopping ADT versus Broadview - If I had to do it again I would go with Broadview (or anybody else!) This is the type of lousy service you can expect from ADT!
Do not waste your money and security on ADT. You spend more than a $1,000 getting set up, then you pay a monthly fee of $29.95. Within six months the sensors begin to fail and you get nuisance alarms. When you complain, ADT tells you it's the batteries. You replace the batteries at $6 each with no effect and ADT tells you it's still the batteries . . . They offer to come out and check your sensor and fix them for about $185 each. Then you start turning off "zones" to stop the nuisance alarms. Finally when you've had enough and cancel, they skin you for another month's fee -- the 30-day notice provision. In brief, ADT's technology is shoddy and their business practices are abusive.
