This blender is very powerful. Crushes Ice into snow, leaves no pieces of frozen fruit in smoothies. If your thinking about spending over $500 on a Blendtec or Vitamix, try the Kitchen Aid blender first. Plus, the clean up on this blender is SO easy. There are no parts to take apart, you just fill 1/3 of the pitcher with water, add a drop of dishwashing liquid, and set it to the "stir" speed, then rinse. Very easy. Also, I was a bit aprehensive buying a blender that did not have a glass pitcher, but the Polycarbonate jar is excellent, lightweight but very durable.
You get a 1yr hassle free warranty. All in all, great buy.
