Product review (4 stars): I Must Have Been Lucky
I was surprised at all the low ratings for this unit.  I've had mine for a little over a year and it has never failed me.  The beer stays cold, it's quiet, and it arrived promptly with all parts. My only complaint is that the screws used to attach the rack on top are too small- one good bump and the laminate on the top of the unit cracked a bit when the screw popped out.  It's not a Sub Zero appliance, but it does the job well enough and I love having good beer on tap after a long day of work.  One final note- be sure to insert a clean rubber washer in the connection between the tap hose and coupler- failure to do so (as I did when first setting up the unit) will create an epic mess.
