I called ADT about a quote for our home, and they explained the equipment they would install and the price. Then the technician arrived for our scheduled appointment, who evaluated the home's needs, and he was eventually and unexpectedly joined by a 2nd ADT person.
Then they informed me that instead of the modest equipment charge I had agreed to on the phone, the cost would be close to $900 for equipment! (Except that with my wonderful credit, I could pay for it in 4 monthly payments.) My husband and I were committed to getting some home security, and after much discussion, my husband eventually over the phone worked out a plan for $400 in equipment, but that was still much more than what we were expecting and had been told over the phone. I am very disappointed with ADT's heavy handed business approach. In addition, they told me they got some existing equipment up and running and that appears not to be the case, so though we paid much more than expected we have less coverage than expected.
And the technical service rep I got on the phone after the installation acted as though he were doing me a big favor to answer my questions.
Bottom line: ADT's business model seems to be one of high-pressure sales, especially once in your home, and marginal customer service after you've signed an expensive contract. Beware.
