The Kitchenaid K150 is the brand's flagship affordable blender. It has a 650 Watts motor, 3 speeds, a combined pulse and ice-crushing function, and a 48 oz jar (1,4 L). Unlike the Kitchenaid K400, it has no other integrated programs, no cleaning cycle, and the motor has a much lower wattage. If you're looking for more power, more settings, and a larger jar size, the Kitchenaid K400 is worth the investment.
