Product review (2 stars): Not staying cool, only 2 years after buying.   Originally had some ice forming at top of the refrigerator as well.
Same comments as "Millie". The ice on top of unit and the popping noises all the time.  Louder than my refrigerator.  Also thought the lower rack was a basket from the picture and it would turn down to get to the wine down there, no it is not it is stationary and you have to lift top rack to access this area.....which is not cool if you have that rack full. Wish I had bought something else.
