It works. I don’t know what else you need to know. Do you need it to open your garage door? BOOM! Consider it done. Do you need it to give you a massage? Well, it doesn’t do that. Besides the massage thing, it works pretty well. Maybe I should go get a massage...
We lost our remote garage door opener. We installed the door 16 years ago and thought we'd have to live without a remote. Our car was programmed to open the door and we also had an outside wall unit attached to open the door. However, we missed the remote we kept in the house to open and close our detached garage. We ordered a replacement. So glad we did. Programing took all of 30 seconds. Wonderful!!!!
