Product review (2 stars): Not Dual Zone
Kitchenaid refers to this as a "dual temperature zone" wine cellar.  It is not.  I've had mine running for a few days and the difference between the upper and lower zone has never been more than 3 degrees.  So either I keep my white wine's too warm, or my red's too cold.

Also, the racks aren't deep enough to fit certain types of bottles, and I'm not talking about rare shapes, but mainstream 750ml bottles.
