Very handy
It's nice to see which tap has what, usually I could remember, but I've poured the wrong thing an embarrassing number of times. It's nice that both sides can be written on, in case you temporarily change a keg, you can just spin it to the other side. The only thing I don't like about it is that it doesn't screw down very far, so there's some exposed threads... Really not a big deal. They erase better than I expected too.
