the most feature that everyone loves in my household is having autofill water pitcher. this is genius. this feature provides with continues supply of filtered cold water at any time that can be infused with lemon or green tea. it takes seconds to refill my water bottle. the ice maker dispenses two types of ice that is different in size, ice cubes and ice bites. this is a very fancy option to have available for making different types of cocktails. the middle door is called flex zone. i have it set up to a deli mode that has a temperature set to 37 f. i am considering to change it to a wine mode with a temperature set of 41f. this literally converts a middle door to a mini wine fridge.
