Rated 5 out of 5 by from Best Installation I Ever Made This is the fifth door opener I have installed over the years. And without a doubt the best unit both to install and operate. I am 79 years old and do not like standing on ladders, which was not a problem as I had it done in no time. I would recommend this unit as the best. Very smooth operator.

Rated 5 out of 5 by from Battery Back up opener I have the Lift-master 8550 garage door opener. I originally purchased the opener because of the quiet belt drive. I have since changed my opinion and appreciate the battery back-up! My wife is not strong enough to lift the garage door when the power is out. If I am not home and the neighbor is not available, she was stuck. Not anymore. Thank you Lift-master!
