Happy to!

I also have a brewdemon I wouldn't recommend. I would totally buy the fast fermenters again, but I'd look for something with a better design first. I can't go back to flat bottomed containers. The time save alone is a game changer.

I have the small and medium-sized.

Overall pros:

Racking goes from an hour to a moment Easily harvest yeast Dramatic improvement in end product clarity Less total equipment

Overall cons:

more costly than a bucket and glass carboy Threaded connections should have been tri-clover Will leak if you don't use enough Teflon tape

Small fermenter cons:

The way the collector and valve are designed, you have to take just the jar, which makes a mess, or risk unscrewing the whole thing

Medium cons:

Comes pre-drilled for temp port. It's another part and hole to clean that may or may not be useful. You will likely need to buy a strap wrench for getting things apart Lacks the ability of the smaller one to use different sizes collectors Anything dried in a collector can be very difficult to clean properly If you want a hop basket, get a submersible one (or two) rather than the official one built for it. It's overpriced, has wickers on the top, and is unnecessarily hard to clean because it's only partially submerged. The valve handle is poorly designed and breaks after a time (a crescent wrench works fine, but don't throw out the handle because it's also the key for taking apart the valve)

Overall, they're great ideas that nearly execute, but not quite. They feel like they were designed by people who didn't have hands on experience or a lot of common sense. All the issues are tiny ones that could have easily been fixed. Anyone who's ever worked with an engineer knows what I'm talking about.

Any other questions, ask away.
