Product review (2 stars): Noisy compressor, small CO2 tank and poor temp control
UPDATED 14April2012.
I've had this keg-o-rator for a few months now.  I really wanted it to be good and started it a four stars.  I now have to drop it to two stars as I would not recommend it.  The price is great, but I would suggest getting one that works from the start.  Or better yet, build your own out of an old refrigerator.  On this model, I like how they added a concave door to a mini-fridge to accommodate a full sized keg (1/2 barrel).  I also like how the CO2 connections are threaded.  Hose clamps are included but not needed for this set up.  Actually there are a lot of parts included that are not used in the set up.  They must be leftover from the original design.  You can tell this design is very different from what is described in older reviews (2010 and before).
I gave two stars because of four issues.  I will list them in order of my concern.
1. When the compressor is off the unit is quiet (of course).  At the coldest setting the compressor kicks on about every 15-20 minutes and it is too loud for a living room.  I have it in the next room over and it is still annoying.  There is no insulation to absorb the compressor sound.  I considered insulation, but that would restrict needed air flow.
2. Originally at the coldest setting the temperature inside is 40-44 degrees.  After reading another post I learned that there is an adjustment screw under the thermostat cover.  I took off the thermostat cover and gave the screw two full clockwise turns.  That made it too cold and I was unable to adequately adjust the temperature with the thermostat.  I had to turn the screw back about 3/4 of a turn.  Now the temp ranges from 34-39 degrees at the coldest setting.
3. The included CO2 bottle is less than a standard 5 pound bottle.  This is probably so you can get it up on the little shelf in the back of the keg-o-rator and out of the way for a full sized keg.  My local supplier does not refill CO2 bottles.  He only swaps out standard bottles.  I had to buy a 5 pound bottle for $100.  Future swaps are only $14.  The 5# bottle will not fit inside the included CO2 bottle strap.  I did get the 5# bottle onto the shelf, but the shelf is too narrow to keep it from falling forward.  This is very dangerous for a compressed gas bottle, but I was able to keep it up there by tying it down with line to the brackets installed for the smaller bottle.
4. My last concern is small, because I have a personal preference for German beer.  Most people will drink use local beer kegs which fit fine.  This unit will not hold a keg of Spaten with the coupler installed.  This unit comes with the US style coupler which matches most kegs.  I like Spaten which required me to purchase a German slider coupler.  I easily attached the new coupler because of the threaded connections, but it was about two inches too tall to fit inside the keg-o-rator.  I took out the keg plate at the bottom of the keg-o-rator and was still off by an inch.

Bottom line is I spent $350 for the keg-o-rator, $100 for the 5# CO2 bottle and $80 for the new coupler (which was optional).  It is noisy and I had to modify the thermostat to get it cold enough.  If I had it to do over again I would stick with bottled beer or build my own keg-orator out of an old (quiet) refrigerator.
