Product review (4 stars): Kegerator and installation
I consider myself above average at most DIY tasks.  This machine made me seem like a novice initially.  The directions or lack of are hard to follow but the system itself is not really that complex.  Honestly, I psyched myself out reading all the negative reviews.  Follow the less than "direct" directions and you won't have that much of a problem.

A few notes:

Piece #5 was located on the plug for the tower instead of being on the tower itself.

The lock to adjust the air regulation with the Allen key cost me about 15 minutes of my life.  It was under the dial and I was only able to get it with the long side of the key.

test out the rubber washers.  Some work for some piece and some don't.  Trial and error.  First pump of air I got sprayed with beer.  All better now .

Other than that it's working like a charm for the first night.  I'll continue to update this post.  4 stars due to the lack of thorough directions.  You may find yourself needing a few trial and error attempts.
