The LiftMaster
Product is original Liftmaster so it works perfectly. I saved over $60.00 using waynedaltonparts, instead of the local service dealer in my area. Once you prop the ladder up to your garage door opener, it literately takes 1 minute to setup the remote. That's it and the old remote becomes canceled out. Full instructions come in the package.
