I’ve got a chamberlain I installed 20 years ago. Came with a lifetime warranty on the belt and motor. I’ve replaced the belt 3 times and they send it to me completely free I don’t even pay postage.

Great job

No issues with sync. Using right now

Most of the apps I’ve used don’t have smooth scrolling or start to lag and eventually crash on me after a while. Not sync. Performance is exactly like the old app.
