This refrigerator has no fan or air vents to circulate air inside the refrigerator. It's fine if you don't open and close the door very much. But if you do the temperature shoots up and stays up for a longer time in a regular refrigerator and my last mini refrigerator. It just isn't as efficient at Cooling. Although I see why they designed it this way because the fans tend to go out. I am keeping it and trying to change my habits and not open it as much..Get in and out quickly etc. Nice shelves.ones I can use instead  of shelves  built  for  cans and bottles.
