I have the FastFerment conical fermenter. It's nice to be able to dump the trub and yeast without exposing the beer. Or to harvest it. I have been a big fan of mine so far. I just installed a sampling port on it with a standard valve that would go on a bottling bucket. This way I can take gravity readings much easier now. The only problem I had was my step bit went a little too big (it was worn out from drilling my keggle for a drain valve) and I had to make a secondary gasket to seal it and keep it from leaking. I couldn't make myself pay for their $15 sampling port add-on when I already had a step bit and could buy the spigot for $3.
I also keg, so it makes it so easy to just fill the clean/sanitized keg and go!
Anyways, I love mine and would highly recommend it to others!
