Product review (2 stars): Buy Cheap, Buy Often
This unit is supposed to be able to be mounted under counter as it has the intake/exhaust through the bottom front grill.  When I first got it, I plugged it in and set the temp to 38 (it's advertised low) and it got there and maintained the temperature.  I removed the old unit (a U-Line from 1998 which had an Ice Maker I wasn't using) a couple of days later and installed the EdgeStar Beverage Cooler in its place.  After doing so, the coldest it would get was 50 degrees.  I pulled it out of the cabinet about 4" and it cooled back down leading me to believe that somehow it had to have airflow/clearance behind the unit.  Since it was not practical to have the unit sticking out of the cabinet, I drilled a couple of 3" holes from the sink side of the cabinet wall and installed a Walmart little desk fan to blow air behind and exhaust the unit - this worked fine for about 18 months.  About 2 months ago, the unit started a very irritating buzzing noise, and then finally a couple of days ago (18 months since purchase) it died.  An autopsy of the unit showed that the buzzing was caused by an evaporator tube resting against the drain tube, and the reason it failed, was that one of the power wires on the circuit board had melted.  Just ordered a new U-Line, more expensive, but since I gave my 20 year old one that still works to a friend I would hate to ask for it back.  Reminds me of an old saying, "Buy Cheap, Buy Often."  If you want to buy a Beverage Cooler that will last just a little past it's warranty period, and not fully cool if installed per it's directions, this is the one to buy.
