I am very happy to have called on "Precision" to help me with the installation of the belt drive Precision 800 model garage door opener. I was totally blown away with how quiet it worked. Unfortunately it only worked fine a couple of times. Trouble was that I needed a new door! Once again, Precision, or rather your fine technician, Nelson to the rescue. After explaining your lifetime warranty and showing me the quality of parts used during an installation, it was a no-brainer to go ahead and order one. Definitely looking forward to that install when it arrives in a couple of weeks. I was also very impressed with Nelson as he patiently and diligently tried to get the door opener to work, admiring his professional work ethic and attitude. Thank you Precision, and Nelson, for a job extremely well done. I will definitely inform all of my friends and associates of your fine service and products. Again, thank you, and much continued success!
