I have the 14 gallon version and while it is nice, I have a couple complaints/concernes...
- You have to be very careful with the lid and the tank not to dent the rim around the outside of each. ON the tank specifically, the thickness of the conical is not such that gives you confidence to withstand much trauma.
- The Racking port seems fragile. Small diameter connection from tank to triclover seems flimsy.
- 2-port ball valves vs 3-port fully disassembling valves
- The way the tank sits in the stand can be funky. Not supported the full diameter of the tank, and if on not pretty level ground, can cause it to sit "off kilter" that makes attaching the arm across the top of the stand a bit "sticky"
That said, I like mine and I find it easy to clean and a joy to use, and I find I can get a slight pressurization (wish I had a CO2 port on mine) for racking. Just be aware of pluses and minuses.
Personally, I am moving to sanke fermenters for cost reasons, but I do like the one I have.
