Product review (4 stars): Cold beer
I bought this somewhere else with kegerator in the name. I wish I'd have gotten it from amazon.  Initially I was a bit unhappy.  It advertises 35 degrees and it wouldn't get below 38.  My Paulaner keg wouldn't fit.  And it made a loud popping sound.  That has all changed.

I found a 90 degree beer line part to help the Paulaner fit.  And I fixed the loud popping.  To fix the popping, I unscrewed the evaporator and left it hanging free.  Didn't hear any popping.  I then put a plastic spacer behind the evaporator behind each screw (a bit of work).  The spacer needs to be big enough to keep evaporator away from back wall.  Moreover,it should be thick enough to not let water freeze between evaporator and wall easily.  Once you do that the popping will likely stop.  it has for me.  And when i fixed that, the temp dropped a lot.  Now if I am not careful, I can get the temp to about 32.  I gave it 4 stars for having to fix it.  Otherwise, I am happy.
