Thru all my years of experience installing garage door openers, I have to say that Liftmaster/Chamberlain has the more reliable openers; Liftmaster garage door openers performance, features and durability are really one of the best in the garage door market. I always suggest to my customers the Liftmaster due to the fact that it is going to last for a long time. Also the two best features of Liftmaster are easy way to change code on the key pad, my customers love that feature, and easy to follow trouble shooting guide.
