Title: Works perfectly!
Review: This unit replaced an aging pulsar, 8 dip switch, opener. There are no physical dip switches in these remotes just an intuitive programming method that mimics them. I programmed both remotes in about five minutes and they work perfectly with our old Challenger garage door openers.Update 7/10/12 We have been using these remotes daily for nearly three years now without issue. I have not had to reprogram or even change the batteries in either unit. Very pleased.
