This Oster Dual Action Blender features 4 powerful ice crushing blades, 2 precision food processing blades, and clog-preventing reverse motor technology that switches blade directions to draw contents down for more uniform blending and chopping.

The 6-cup dishwasher-safe glass jar is thermal shock tested for long-lasting durability. Plus, the included 20 oz. Blend-N-Go cup attachment lets you make smoothies and shakes and then take them to go with no mess.
