This smoothie blender is very lightweight, with a plastic blending jar. I used the smoothie blender to chop walnuts, which it did pretty well. It has 10 speeds and is very versatile. Very easy to assemble and use. Grate, Ice Breaker, Milk Shake, Smoothie, Icy Drink, Stir, Aerate, Puree, Crumb and Chop. I highly recommend this blender.
