Garage Door Opener Installation

Old opener from the 90s finally died. motor was completely burned out. Called Instant Garage Doors (IGD) and Isaac came out next morning. Recommended LiftMaster 8550WLB belt drive with battery backup and MyQ. Had it in his truck, installed same day, programmed everything, set up the app on our phones. The difference in noise is incredible. Our bedroom is above the garage and we used to hear it every time. Now it's whisper quiet.
