I have had zero problems with it, and I really like it..... it is the one you can order through Northern Brewer. I don't have beer hooked up to it all the time though. I have some 2.5 and 3 gallon kegs. So, often, I will brew a batch of bitter and put it into a 3 and a 2.5 gallon keg. That way I can put 2 gallons on the beer engine when I have friends over or something like that, to make sure we drink it all up. Or, if I have a gallon or so left of some kind of beer (bitter, porter, mild, etc. ) I will throw that on the beer engine as it gets low.
the keg just sits under my bar at basement temp (55) and I open the pressure relief valve - so it is getting exposed to oxygen at that point and so it really only has a couple days of life.
It takes 10 minutes to clean it up and run hot water, star san, line cleaner etc. through it when I am done using it. But that is not a big deal, and well worth the little bit of extra effort to serve a beer in a way that makes it even better.
