Came out to fix alarm going off. Was not a regular customer but gladly fixed it for me. Did not try to hard sell other things but after chatting with him, I decided to get the system. My setup gave some challenges, but he stayed with it until done and double and triple checked it working before he left. Good guy to deal with.
