Review on Firefly Allstar Keychain Compatible Better by Cameron Kennedy

As instructed, I opened the remote and flipped 9 micro switches that matched my Allstar 9931R on the garage door. The numbering on the DIP switches was so SMALL that I read them upside down on the first try. (I even wore glasses!) When the remote didn't work, I checked the switches again and found my mistake. I reprogrammed the DIP switches to match them and while the case was still open I tested the remote and it worked great. I cut a small piece of bubble wrap (which the remote arrived in) and placed it on top of the battery so it fits snugly on the case and doesn't move as another buyer mentioned in a review. It works well and from a distance of 20+ feet it's a great buy and I will buy again for added comfort.
