Title: Doesn't work on Liftmaster
Review: I first had to reprogram both my receiver and my existing remotes, because the CLT1 doesn't have a "0" setting for its DIP switches. That was annoying and tedious but not hard. I then followed the programming instructions for the CLT1 precisely and it didn't work at all. I also tried reversing the on-off settings as another user suggested, and that didn't work either. I'm returning it tomorrow.
Is the review positive or negative?
