Veritas - they're great. They're well constructed, they're real conicals, and the temperature works well. You can heat it up quite a bit (I've never had to go more than a handful of degrees to be honest) and the cooling does about 30 degrees from ambient (warning: You have to fill the thing up as the fans are near the top of the fermenter. If you don't, you risk ice building up and having it be less effective.)
I highly recommend them -- they're the absolute best home fermentation solutions outside of a non jacketed steel fermenter inside a fridge customized with a temperature controller but those usually do not heat. What the average homebrewer doesn't realize is that temperature control is paramount and even a couple degrees can make a significant difference in the finished product. Ultimate control is important.
You won't be sorry. I want a second one because they're so good and because fermenting in corny kegs is not that good.
