The chiller is able to cool 8 gallons of glycol/water mixture to below freezing and keep it there, even in a garage at 75F. I haven't been able to hook it up to the fermenter yet to test. But it appears to do exactly what it is supposed to do. The default settings are reasonable and make it easy to get started.The reservoir is too small to hold more than about 3 of the larger pumps that MoreBeer sells, so it isn't clear how to take advantage of all of the 5 in/out ports.Once you route all of the internal hoses, it is difficult to impossible to remove the inner cover for the reservoir. Hopefully that will be a rare event.The compressor is fairly quiet, but I am glad that it is in the garage instead of in the house. It would get irritating if I could hear it in my main living space.The unit was packed in thin styrofoam that was busted to pieces when the package arrived. However, the unit appears to be undamaged and functioning properly.The instructions are a bit lacking. It would be nice if there were a diagram of the unit that labeled the parts, etc. And a little more detail on steps like "install the drain plug" - like, where is the drain, what is the plug, how do you install it - would be helpful.Overall a solid product, and I would buy it again, especially at this price point. But there is room for improvement in a few areas as listed above.
