I had this blender for about 2 weeks, when it decided to jam up and my last smoothie had a torn rubber washer and broken glass in it. When I called Waring they told me that it is not meant for frozen fruit (! - what else would you put in a blender?!), and did not offer to replace or repair it. Spend your money elsewhere...
