I bought these and have each button connected to a different garage. The instructions are very clear and easy to follow. Definitely recommended.
I was just looking for a replacement garage door opener after we moved houses and this product was great.
Son bought a new home and the garage had only one remote which he shared with his wife. This arrangement wasn't working well. I got these remotes at a much lower cost compared to the garage door actuator brand. They were easy to program, work like a charm and battery life appears to be very good.
Very easy setup (just follow the directions, not sure what some of the other reviews were talking about) and much more sturdy than I was expecting.
Received quickly, fairly easy to program, hoping they will last a couple of years.
