I just got my beer gun from Blichmann Engineering today, and I love it. I've been using a traditional counter-pressure filler for a while now, typically don't bottle but now that we're going pro kind of have too, and in the time it usually took me to bottle a case of 22's with the CPF, I bottled 2 1/2 cases with the beer gun. It's easy to use with one hand, and no more having to worry about the stopper sticking in the mouth of the bottle or adjusting the filler for different size bottles. I wanna hear what other people think.
