Title: A burglar's dream of a device
Review: I bought a CLK1 for use with my Liftmaster (1997) opener. It works fine for THREE openings and then resorts to acting simply like a remote (press any key and the door opens).The instructions are awful - I have a Liftmaster with off-white buttons on the remote and nowhere do Chamberlain give instructions for this (even though it is listed as being compatible) - you have to try it as an 'orange' or 'green'.A complete waste of money with the worst printed instructions imaginable.
