This fridge is not only energy efficient, it is also very flexible for storage. We didn't think we would need the door-in-door but it's very useful and doesn't waste the cold in the main compartment. We also like the fully-convertible middle drawer to use as refrigerator or freezer space when needed. We like the counter depth size too, as it doesn't stick out into the kitchen much. Great product, works well, nice design and mechanical components. We trust LG appliances!
