Buz wonders if they are licensed to do alarms in Maryland. I wonder if anyone has ever tested one of their alarms, or been broken into. How do you like the "service". Hate to say it, but that residential industry has sort of evolved into a racket (this is not my original thought). Nobody wants to upgrade your alarm; they only want to sell you a new system
