Headline says it all. Was a bit skeptical, but I pulled these out of the box, and within about 3 minutes had both of them programmed -- one to each of our openers. Press "Learn", hold the remote's button, light blinks, done. Couldn't have been easier.

My Liftmaster opener has the purple learn button. The remote already had a battery installed and worked immediately after I pushed that button. Here's a tip regarding the clip installation. Use two sets of pliers to bend a slight vee into the end of the tab on the outside of the hole at the end of the clip. this allows the clip to clear the raised plastic button shaped keeper that aligns with the hole in the clip. Push the clip in so that the clip extends past the side of the remote then rebend the clip back flat again. then pull it back and it'll pop in place when the button and hole are aligned.

The garage door opener that comes with the Liftmaster is $40. I took a chance on this product and am very satisfied. It programmed easily with the garage door Liftmaster. It was much less expensive than the model that comes with my garage door opener.

Worth it. Works great was able to programme both controllers with out a problem. Mines have purple learn button

I received these today and programmed both remotes with no problem! I have a sears garage door with the purple fittings.
The only deal is that I failed to read the technical review and didn't realized it came with batteries! I ran to Home Depot right after work to purchase the 2032 batteries. I wanted to be ready to rock and roll once I got home as I knew that the package had already been delivered! (sigh) I guess I can save the batteries or get a refund. None the less I am pleased!

Thanks!
