This thing cools wort like a boss. With the correct flow rate and reasonably cool ground water temp you'll be able to cool an arbitrary amount to near pitching temp in short order. You knew that though. Function is top notch, but...My brew setup uses Blichmann quick connectors everywhere. The Therminator requires garden hose connectors for the cooling water - which means I have to use adapters to make this Blichmann product work with other Blichmann products - silly.Second, the edges on the back-side of the chiller are sharp. You _will_ cut yourself. Especially if you use Blichmann quick connectors which require you twist something with your fingers right next to raw metal edges.Third, It feels like it's going to slice your hands when you pick it up. It's very uncomfortable to handle which you have to do when cleaning. This might seem picky but at $200 and with the Blichmann name it's not.Last, the mount is functional but for something you have to take on/off to clean and store it doesn't make sense to use bolts vs some type of bracket. I'm OK being wrong on this one because it does work well and comes with a solid mount.Before this I used a DIY counterflow chiller that worked but had crappy connectors and looked lame. If I was buying today I'd look at the compact copper counterflow chillers that likely clean/sanitize/dry better.
