Product review (4 stars): Working well for us.
Installed undercounter in December 2015 and it's still working just fine.  Noticed last night a buildup of ice so pulled it out, unloaded, unplugged and let the ice melt overnight.  I suspect the ice build up is from it bouncing open and running constantly about 24 hours.  Be careful, it can look closed and be open a crack.  Best to close firmly with a hand and not just push shut.

Low setting of 38 keeps it about 41 degrees constantly, very reasonable in my opinion.  We keep it full with wine and cans.  Four stars because shelves are not adjustable and I can't remove to clean either.
.
We solved the wide spacing of the shelves by purchasing several of those little rubber mats that hold four cans of soda for two of the wide shelves, and they keep wine bottles/beer bottles from rolling, allowing us to stack a second row, almost doubling usable space.
