I haven't used the bottle opener yet but have mounted it on a keezer I'm building. I like the somlle design more than the others and the magnets on them are very strong. The caos are easily captured even tossing them at the board. The only thing I might change is a good coating of poly on it to match the collar it is attached to a little closer. (I don't know if this will make the board too slippery)
