We have been using Alarms R Us for twelve years. We have stayed with them for so long because there is no one better than they are! The last time they were here everything went great. They revamped the entire system because it needed a few tweaks and updates. There were some batteries that needed to be replaced and a couple of pieces that were out of line. They were not properly aligned with the windows and needed some tweaking so they took care of that for us. Their prices are fantastic and we know them personally. They did a great job and they were perfectly friendly.
