The 81LM works great on my craftsman opener, which has a green program button and a light grey antenna wire. I had them both programmed in under a minute!

It works and was easy to program. Works with older models. I have a Liftmaster 7200 with the green program button. I gave it 4 stars because it doesn't have the light on it like my other remotes. The light shows you that the remote is working, and might give you some indication that the battery is dead, but this model doesn't have one.

I bought this as a remote for my car since I just leased a house with a 2 car garage with some friends. The owner/retailer handed us one remote and I let my roommate take that one while I went on the search for one. I checked the motor for the garage and it was a Liftmaster with a green sync button. Bought this when I found it was compatible with green sync button Liftmasters. It came with instructions how to sync it and within 3 minutes of opening the box we had 2 garage openers for our garage. Very pleased.

This product was easy to program to my existing door opener head unit. Shipping was fast and the price was reasonable.

This was VERY EASY to program. I had it programmed in less than 30 seconds and it was cheaper than all the other remotes out there including the ones on Ebay.

Brought a third car (pickup). Got tired of going to other car removing garage door opener and walking out to other car then closeing garage door. Super easy to install. Just push the red button on the garage door opener then push the open button on the transmitter and that is it.

The remote came in a timely manner and works perfectly. Fortunately, I knew the model number of the remote needed.

My Craftsman opener made in 2000 has a red learn button, but that does NOT made it a Security+ unit for which a 97xLM series will work. For purposes of a new remote, one must treat it like a Chamberlain or Genie unit vintage '93-'96 that has a GREEN learn button. Thus, buy either an 81LM series remote or a universal like the 375LM. If you buy the 375LM, program per instructions but with 4 button presses, not 2. Also, must press and immediately release (not hold) the button following each of the 4 presses (instructions are also vague on this point).
