Product review (1 stars): This thing pops and cracks when the compressor turns on.
Dont recommend this unit.  I have tried to get it swapped with a different unit, with no luck.  Kegco claims the popping is normal, which screws you out of claiming it a faulted product.  So in order to return it, should you not be happy with it, it will cost you $240.  Get another brand, Kegco is poor quality.
