Awesome fermenter, PITA gaskets.
Love this fermenter, and it makes bottling/kegging day a breeze. Like others have said, the lid gasket is a real pain to deal with, as are the gaskets in the butterfly valve assembly (don't screw the valve, or the jar on too tight). Another review mentioned how difficult it is to collect trub and said a workaround would be 'to immediately open the valve fully when you fill the fermenter with wort thereby allowing the Mason jar to collect the trub. Then you close the valve after fermentation is done and remove.' THIS is how they designed the fermenter to work (email them and ask). Transfer the wort, aerate, pitch yeast, attach mason jar, open the butterfly valve, and ferment. You may have to empty the mason jar twice if you are using a lot of hops (or a high gravity ale), once after fermentation ends and the trub packs down, and again after cold crashing, but I've never had an issue with trub getting into my bottles or kegs afterwards.

Needs more work.
I really wanted to like this fermenter. The main reason I bought this was to avoid transfer to a secondary. the trub that collects is, as we all know, quite dense and thick. When I open the valve, I can get only about 50% of the trub and that's with sucking off a good amount of beer, too. Then, when you want to rack to your keg, the tubing attaches to the bottom of the fermenter so you end up drawing the beer through the remaining trub and yeast.
The workaround would be to immediately open the valve fully when you fill the fermenter with wort thereby allowing the Mason jar to collect the trub. Then you close the valve after fermentation is done and remove.
The other is to drill a spigot a few inches above the rain port to allow you to rack off the trub and not through it.
But I should have to have "work-arounds". It seems this wasn't thought out enough or put out with little internal testing/actual brewing with it.

The silicon gasket comes loose every time the lid is removed and is difficult to put back on.

No issues!
I love this fermenter! i noticed that one of the reviewers talked about having to have work arounds while collecting true when it clearly shows that you should have the butterfly open wth a mason jar when you pump through your chiller into the bucket. if you do this you will have no problem with collecting trub and harvesting strains for future use. i think that what i love most about it. in my other SS conicals you have to open valves to transfer over the trub but this takes that step out of commission. Love this fermentor and have brewed some awesome beers off this system. Just bought two more to add to the fermentation chamber!

Convenient but a little messy
A little messy when removing the jar but much less work than racking twice. I needed to dump the jar 3 times but I dry hop. 1 oz of hops will almost fill the jar. A little tricky to rinse the valve threads before replacing the jar but can be done with a rinse or spray bottle. Beer turned out great !

It's ok
I just got it put together and the first issue I can see is the lid clamps, they are bendable plastic and I'm sure will not last. The second thing I noticed is the plastic legs are not as sturdy as I thought they would be. I hope it holds up for $200 worth of brewing.

Very good fermenter ...
This fermenter is great.
Remove yeast and trab for secondary fermentation with the turn of a valve.
When adding priming sugars I first lay down a balnket of C02
then slowly stir in the sugars.
Bottling is a snap with the included adapter.

Greatly improves the brewing experience!
I waited to write a review until after bottling my first brew with the Catalyst. I've been brewing for 3yrs, and found I was brewing less recently due to the racking/cleaning just being too time consuming. I hoped this fermenter would help simplify things, and it really delivered!
I was a little concerned about some of the reviews, but I found none of the concerns raised were significant. The seal around the lid does come off easily, but getting it back on isn't that tough. If you've ever had to replace a tube in a bike tire, it's similar to working the tire into place on the rim afterwards. Once you get it down, it isn't too bad.
As mentioned, have the butterfly valve OPEN with you add the wort to the fermenter. I used a larger 32oz mason jar, and it filled with trub during primary fermentation. Put a pan under the jar when removing it as there will be spilling from the full jar. I then put the smaller (sanatized) jar onto the Catalyst for secondary fermentation. It too filled with trub by the time I came to bottling. I closed the valve, replaced the jar with the bottling attachment, stirred in the bottling sugar and completed bottling.
As others have mentioned, clean-up is also much simpler than with carboys!
I can't say enough about how much easier the entire brewing cycle was compared to using primary/secondary carboys and racking.
I rarely write reviews, but this product is awesome! It's the best brewing equipment investment I've ever made!

Good but coule easily be great!
This is a good entry level conical fermenter, the only 2 suggestions I have... Make the tank itself out of amber or brown plastic instead of clear... Provide the option of having a thermometer (other than stick on). The only small issue I had with this during my first batch is that the valve leaked while I was aggetating prior to pitching... That's a minor issue since it didn't persist and I have already picked up an airstone to avoid throwing my back out on a 5 gallon batch. I will get a little wet while sanitizing but I can do that outside to be safe.

Need a little practice.
Out of the box, the quality of the product is outstanding. Easy to assemble and I could barely wait to brew my first batch. Went online for much needed advice, and I still need to work out a few issues. Double straining wort, more cautious opening of the collection jar and adding the Bouncer filter to the bottling process to name most of the changes for planned second batch. The conical design is great, but when bottling occurs at the very bottom, sediment is an issue. I will have a homebrew and try again!

When going to bottle from the catalyst does there seem to be problems with getting the priming solution to mix evenly? Best way to go about adding the priming solution without additional oxidation?
A shopper on Nov 10, 2016
BEST ANSWER: Great question! You could make add the priming solution as normal and add it directly to the beer in the Catalyst Fermenter. It should be very lightly stirred with a sanitized to provide proper mixture.
Another option would be to use our Fermenter's Favorites Fizz Drops (SKU: 40928).
Cheers, Todd J
Watching the video, each time the valve is opened a plume of air bubbles up through the fermenter contents. Wouldn't this introduce oxygen to and risk oxidizing the finished or nearly finished beer after all the care we've taken to protect our beer from O2?
Keith G on Jan 6, 2017
BEST ANSWER: fill the empty jar with C02 before you screw it back on.
C02 is heaver than air and will stay in the jar till the valve is opened.
Is this able to do wine as well?
A shopper on Nov 28, 2016
BEST ANSWER: You could use it for wine, however it may not be big enough for most of our 6 gallon wine kits as you need a little more headspace for wine.
It says you could use it for wine- but has anyone actually tried it with wine? If so, how did it turn out?
A shopper on Feb 14, 2017
BEST ANSWER: This is a really nice fermenter for beer or wine. Very well made and easy to clean.
The valve and collection jar saves you some time and work while protecting the ferment from oxygen.
Does the wart need to be cooled prior transfer or can it be hot with out fermenter damage?
A shopper on Mar 3, 2017
BEST ANSWER: You should cool the wort before transferring it to the Catalyst, that would be the best practice. That said, the vessel is said to be able to withstand temps up to 230 degrees Fahrenheit, according to their website. I think I'd cool first anyway, as it would not cool very quickly once placed in the fermenter. -Mike W, Midwest Supplies
Is there a version for 10 gal batches?
A shopper on Feb 22, 2017
BEST ANSWER: HI there,
The Catalyst currently only comes in this size. Cheers!
Is it possible to add a blow off tube to this? I see nothing about an airlock at all.
