Product review (4 stars): Decent Tower cooler.  Nothing to complain about.
Seems to work well.  I don't run it constantly.  Basically, I turn it on about 15-20 minutes before I think I'm going to poor a beer.  Definitely helps reduce the initial first biast of foam.  Super easy to install.  I was fortunate that my kegerator has a small hole already in the back that you can pass the electric cord through, so I didn't have to worry about drilling.
