Works like a voodoo charm! Stupid easy to program. Has good range and the small size is very handy.The fob works great! Although, my husband found that putting the fob in his pocket caused it to engage. Every time he bent over or sat down the garage door opened. It’s now off his keychain. He’s had to leave it in the house or vehicle, which isn’t exactly what he wanted to do.Pushed the green button on the opener and then on the remote ...and viola! It works!We had been needing extra garage door openers for years. Since finding out about these, I have ordered several. They work great. They are small enough to carry in your pocket or purse, or on a key ring. I am totally satisfied with them. Thank you.Works great. Was very easy to program to my garage openerLove the size of this opener and the fact that I can hang it from my keychain. Was super easy to sync with my garage opener (green button).it work on my craftsman garage door opener with green leaner button. better than the $115.00 original craftsman remote.worked for me and i ordered one more and both are working.
