This is good for keeping drinks cool.  Not for anything that requires true refrigeration like dairy.  We have AC but in the summer when it is really hot outside high humidity this will hover around 42 degrees regardless of what you set the temp at.  In the winter it will freeze the beverages if set at 39 degrees.  We have our house thermostat set at a constant temp.  I think it has more to do with humidity as far as the temp fluctation of the refrigerator.   When we ordered this we specifically wanted one that could be put in cabinets.   Needed front vent.   The specification said it could be set in cabinets.  The refrigerator we received however specifically said do not recess in cabinets.  So beware you can not install this it has to be in the open freestanding.
