The Liftmaster 1/2 hp screwdrive, is a remarkable product it seems to cycle doors for long periods of time with out any serious issues, this opener is reliable, inexpensive and is an easy install.

I have very seldom even had to service these openers in the past, the one downfall is that the screw mechinism, makes a lot of noise… They have recently (early 2008) changed the screw mechanism and had some problems with it but since then liftmaster has seemed to get all the bugs out of it… I give this one a Rating =7
