Product review (1 stars): FAIL: Not a real refrigerator!
I have one that only worked marginally for a couple years then quit.  It's not repairable.

Even when it worked it would only cool off to some number of degrees below the outside temperature making it only suitable for keeping drinks cool, not cold.

In my opinion this is a total failure as a design.  It has two thermo-electric modules instead of a compressor like a real refrigerator.  Apparently two modules is insufficient to cool this unit and the modules are unreliable and have a limited life.

Steer clear of this 'appliance' !
