Product review (3 stars): Double Tower Setup
I would echo what I read in a lot of reviews, it doesn't keep beer that cold.

My big complaint is that you can't customize this kegerator to have 2 beers on tap.  The tower is 2.5 inches in diameter, which is too small to add an additional tap to (most towers are 3 inches or bigger).  It might be possible to squeeze the equipment needed in there, but I'm not sure it will work and don't want to be left with a hole in the tower.

Also, the description says it fits 2 5 gallon kegs.  Maybe it will fit two home-brew kegs(don't know didn't try), but only the smallest 5 gallon (1/6 barrel) kegs I get from local breweries will fit (some have extra plastic protection on their kegs making them wider).  Even then, they would only fit if I raised one a few inches off the ground with a block so the widest parts of the two kegs wouldn't come into contact.  Even then, I had to find a way to strap the door shut or it would come open. The two kegs were squeezed in there really tight.

Bottom line, this is a good entry level kegerator, but don't expect to get 2 kegs of any size in there.
