Review on Bison Designs Carbonator 100 Percent 38 Inch by Tony Doan

I found the first one years ago and bought it on a whim. It was great at the time, also because the lack of metal meant I could wear them at airport security. I also appreciate the simplicity and light weight. In addition, he proved to be durable. So this is the third one I've bought and my wife now has one too. I'm a fan.
