Had a liftmaster installed w/ my new double door 16 yrs ago, crazy expensive at the time. Lasted 12 yrs. Found a Chamberlain belt drive, looked identical, put it in myself.
Bought a Wayne Dalton once for a single door, biggest POS you could imagine. Couldn't get the down/up travel adjusted for shit, opened it to find the adjustment screw wouldn't engage the shaft for any adjustment. Returned and bought another Chamberlain, worked right.
I'll probably stick with Chamberlain from here on out.
