I have been trying it out with mixed results. So far it worked great on 15 Bbl batches, but on a 30 Bbl batch it does not compact enough for me to get clear beer from the racking port. I have no racking arms, so that doesn't help. I get real clear beer at the sample valve but its too cloudy at the racking port. On the 15 Bbl batches it worked real well and dropped bright quickly. Very easy to use. From what I gather from other posts and talking to other guys who are using it, the stuff works quick but simply does not compact as well as isinglass so it depends on your set up wether it will work or not. I would say if your interested its worth a shot.
