Product review (4 stars): Great straight out of the box, but some tips.
I have had for a month so far.  Make sure all your connections are secure and tight, I leaked through a whole tank of co2 in less than a week.  Went through and wrench tightened, no issues since.  I have already gone through three 1/6th barrels of some awesome local crafts.  Yum.  Be sure to calibrate your co2 pressure for each unique brew.  One IPA poured perfect at 5psi, a different brewery IPA at 10psi, while a Jalape&ntilde;o Pale Ale did great at 8psi.  Another tip, get some smaller snifter style beer glasses, the smaller pours gets you back to the kegerator more often.  Because, you know, actually pouring the beer is almost as fun as drinking it!!
