This "cyclone" blender only lasts 3-6 months, even if you are simply blending liquids. The blade bottom teeth break off and the cost of repair, since you need 2 separate parts, is more than the cost of the machine. DO NOT BUY!!!! This is advertised as the top of the line in 12 speeds. It's the bottom of the heap and B&D are not helpful at all, even with a warranty.
