After testing both the Fermentasaurus and Fermzillas and selling many of them both it's our opinion that it's much easier to use the Snub Nose Fermenter which doesn't have the valve assembly on the base. You can still dry hop, still harvest yeast if you chose, still transfer under pressure but not have the issues of leaking, stuck valves, difficulty with cleaning etc. for cheaper in a smaller space for the same volume and the pressure kit is included in the price!
