Has anyone used one of these?  http://www.northernbrewer.com/fastferment-7-9-gallon-conical-fermentor

I ordered a Brew Boss and the fastferment came with it and while it seems like a great way to get into a conical I am curious if anyone has had any issues with it sealing up.  I pitched the yeast on Sunday and it fermented for about 2 days and then by Wednesday morning it was finished.  I normally get at least 6 days of fermenting done.  Does anyone have any experience with this thing?

What yeast, what gravity?  I have had a few only take 2 days...

It was a Dale's Pale Ale Clone.  Yeast was SafAle US-05....We drank a little to much product and forgot to take the gravity up front but the gravity is supposed to be 1.065.

I have one.  It seems to me that everything moves along faster when using it.  I'm no expert on fermentation but 2 to 3 days of active fermentation are normal for me.

Interesting, I hope that it was enough. I actually pitched it again to see if it would ferment anymore and it wouldn't.  We will see. Thanks for the reply
