I ordered this replacement board for my 20+ year old garage door opener that failed to operate with the remotes. The communications was very good from when I initially placed the order, to when it shipped, and when it arrived.
The installation is very simple. After removing the mount and circuit board from the opener, I swapped out the circuit board to my rear mounting cover (four or five screws was all, and very simple everything lines right up), installed the new board/mount into the opener, programmed my remotes and was working in under 20 minutes. Definitely would order from Gate Openers Unlimited again.
