I mostly use the simple, freezer on top, refrigerators. In the past (maybe 15 years ago), they did a good enough job. Lately I have noticed that the cold air distribution to the refrigerator has been terrible. In some units, food places in the back of the fridge will freeze while the front remains cool rather than cold. Other units show the same issue but top versus bottom. I feel like a tiny fan to help distribute the air would fix it.

I do want a Subzero but, Jesus...they are so expensive.
