I’ve been using the Liftmaster 8500 for about 6 months now and I think it’s time for a review. In general I like it very much. I especially like that it allows the garage rails to be mounted very close to the ceiling, making the garage feel much more spacious.
One downside I saw was that the garage door installers had no clue how to install these. It took them 3 tries to get the rails installed (mostly) properly.
Overall I’m pretty happy with it and would recommend to a friend.
