Product review (5 stars): There is a Learning Curve
I was given this item as a gift, but feel inclined to post a review here.  The longer you read this, the more you will believe that I actually have one and won't be deterred by not having the Verified tag at the top.
I definitely went through some growing pains with this unit. The foaming problems, which are prevalent with bad reviews, are caused by a number of factors.  Some of those factors are uncontrollable by the end user(you/me), as in, some kegs just fail (pressure).  I found myself fiddling with hose length, temperature, pressure, leveling, tightness of connections, etc.  I even went on and replaced the stock 5' tubing with a 10' tubing and fixtures set thinking that would solve my issues.  It actually helped, but only for a type of beer that has a specific gravity.  Yeah, another factor you have to deal with.
Bottom line, is that you can find the perfect pour, but there's a learning curve even for the most experienced person.  Right now my Fat Tire is pouring perfectly at about 34 degree, no complaints.
