Product review (4 stars): Warm temperatures, not enough beer line for high altitudes
First off, I live in Denver, CO (the mile high city) and there is not enough beer line to get a decent pour.  I changed the tower out so I could pour 2 kinds of homebrew from 5 gal soda kegs.  When I did, I added a couple of feet of beer line (from the included 5' to 7').  The line has to be about 7 ft long to pour decent here.  Keep that in mind if you live in high elevations, this will NOT pour right with the included equipment.  Another problem is temperature. I have it at the coldest setting and it is about 40 degrees.  Beer needs to be at most 38 for a good pour.  After reading the reviews on here, I am going to be calling them requesting a service call.  If they can fix the temperature issue, this is a decent unit for the money.
