3 Part Blending System

With the combined power of the blender's vortex-creating ribbed jar design, and unique asymmetric blade, blending is a breeze. Add to that the smarts behind the Intelli-Speed® Motor Control, which automatically senses contents and maintains the optimal speed for a better blend.
