Our Verdict

KitchenAid K400

KitchenAid Diamond

The KitchenAid K400 and the KitchenAid Diamond have different strengths. The K400 has a better build quality and makes a smoother puree with big batches of fibrous ingredients like multiple servings of a kale smoothie. It makes more uniform crushed ice. On the other hand, the Diamond is much easier to use for recipes like nut butter. It's also easier to clean.
