We had an old alarm system (>20 yrs!) from Pre-lock and I started shopping around for a replacement. I got a proposal from another company but decided to give pre-lock an opportunity to present their new offerings. Paul, the president came over and helped me read through the small-print of the competitive offer that I had obtained. He then proceeded to give me a proposal for a state of the art system. The cost, including labor, was very fair. The system was installed today and the technician was very knowledgeable, discreet and he left the place quite clean. I am still in the process of learning the system but so far, everything seems to be OK.
