Imagine a refrigerator where food doesn't hide in the farthest corners and you can survey your inventory without opening the doors. It's clear that the transparent, bi-directional doors are not the only innovative features of the DUO refrigerator. Family members can use the voice memo system to leave messages for one another like the notes that are often pinned to traditional models and a removable bar caddy lets you roll chilled beverages and glasses right to your guests.
