Product review (4 stars): Great unit so far!
A great unit, follow the directions and it works as advertised. I've been using exclusively non pressurized kegs with the co2 kit and have had no issues, currently on my 3rd one. Keep the pressure at the recommended settings (.4-.5 for most beers) and the beer stays fresh without being foamy.  The first beer out of each keg is a little foamy but not too bad and after that it's good to go. Temps stay right at 30deg below ambient, so with my house at 75deg in summer the beer stays 45deg (hold temp down button until it beeps to get the temp).  I think it would keep it cooler if there were a gasket on the door,  so I will add one - only reason I didn't give it 5 stars.  Beer after a week tastes the same as the first, which was the goal. Each keg takes one co2 cartridge and one had just enough pressure left to clean the lines, the other didn't.  Bells Oberon and Breckenridge summer bright were very good,  Bitburger was just ok.  I ordered another tap so I can adapt one to fit growlers so I can increase my variety more and decrease my commitment to a six pack worth instead of a 12 pack as there are a ton of places that fill growers locally (at least 70-80 different beers available) vs. only half a dozen different 5 liters available around here. It's great to have beer on tap at the house without having to commit to 60 (1/6 keg) of the same beer in a month.
