Product review (4 stars): After manually adjusting thermostat, works wonderfully!
So I was skeptical to order this kegerator, but after reading some of the more recent reviews I decided to take the plunge.  Unit arrived in 3 business days, and didn't take too long for me to put together.

I ordered a 1/2 keg, and went to my local welding supply to get the CO2 tank filled.

When I put this kegerator to the test I was initially disappointed that it seemed to be hovering in the 46-48 degree range.  I tried to pour a beer, but it just had too much foam.

  After reading some recommendations on some forums, I took the faceplate off the thermostat, and then found the calibration screw.  I gave it a few turns clockwise, and waited an hour.  When I came back the temperature was now 42 degrees.  With another couple turns of the adjustment screw the unit was staying in the 36-38 degree range no problem.

After attaining the proper temperature, the beer poured PERFECTLY at ~9.5 psi.  Very excited I was able to get it working, and now I can relax and enjoy fresh draft microbrews at home :-D

P.s.  As other reviewers have stated there is a rubber ring that goes under the tap tower, but it does not tell you to install it in the instructions.  The tower isn't very sturdy unless you put the rubber ring under it.  Once I put it under, and twisted the tap tower to lock it in, it was sturdy and solid.
