No more pulsing, shaking the jar, or hand stirring needed for excellent results with the Calphalon Auto-Speed Blender. This blender senses the mixture in the jar and automatically adjusts power to maintain blade speed for perfectly blended results. Dual-direction blades and a 1,100-watt motor easily pulverize the contents. The 2-liter Tritan jar is dishwasher safe and BPA-free. An All-Metal Drive delivers reliable durability and a digital interface provides intuitive control. The included Blend-N-Go smoothie cup lets you add ingredients and blend inside the 25-oz. cup, then take it with you.
