Product review (4 stars): Does it job, but not perfect!
I purchased this kegerator about a month ago now.  It has worked as designed since I purchased it, with a few minor issues.

First, I wanted to comment on the power usage.  This thing is incredibly energy efficient!  The first thing I do with any appliance is I hook it up to a kill-a-watt meter.  When the compressor first kicks on, it draws ~650 watts (which is enough to make your lights dim), but the power usage quickly drops from there.  Within 5 seconds, the unit is drawing ~100 watts.  After 30 seconds, the compressor is running at its optimal level and is drawing 84 watts.  84 watts is less than a 100 watt incandescent light bulb!  Who would have thought a fridge could draw less power than a light bulb.  My kill-a-watt is reading that the fridge has consumed 5.66kWH in 184 hours of being on.  That comes to an average of .739kWH per day, to keep a half barrel keg at 38 degrees Fahrenheit in a ~72-74 degree house.  I think this is quite impressive.

The fridge is able to do this for the following reason; there are no fans inside or outside the fridge to speed up the cooling process.  The outside of the fridge is actually the heat sink for the hot coolant.  So when the fridge is on, the left and right side will get warm to the touch but this is normal.

As stated by other people though, the compressor is louder than I had hoped.  Luckily for me, I put it in the corner of the kitchen which prevents it from having a line of sight.  This seems to help the noise, and you will quickly forget it is on.

Another negative comment, I can't figure out the proper way to connect the keg coupler to the line that runs to the handle.  The o-ring they want you to use does not fit and it caused beer to come out at the keg connection.  So I used a larger o-ring and that stopped the beer from coming out at the connection.  But there is still a good amount of foam that comes from the first pull of the day.  This may be normal with all kegerators though.

My last comment, even though its not the fault of the fridge.  When I went to have the 2.5lb tank filled, I thought everything was normal.  As I was driving home from having it filled, the pressure cap on it blew filling my car with white smoke and scaring me half to death.  I took the tank back to the place I had it filled, and they actually decided to give me a 5lb tank instead (free of charge).  This problem may have come from the place where I filled it, but I got a 5lb tank out of the deal for free.  The tank fits in the kegerator no problem!  I simply used zip-ties to connect it to the tank restraints inside the kegerator.

Overall, I am satisfied with the purchase.  Lets just hope that the quality is there and the fridge can last for years!
