We were searching for a blender that could power through kale and frozen fruit breakfast smoothies and this model is it. With just a push of the pre-programmed smoothie button, this blender quickly begins to automatically mix, oscillating left, right, which pulls the ingredients down towards the blades then finishing at the highest speed. I no longer have to stop my blender to periodically push down the ingredients, thanks to the powerful dual direction blade technology and wide glass jar. The end result is the smoothest product with only the smallest of particles remaining. Works beautifully for blending ingredients for soup. This blender is relatively quiet and easy to clean. Smoothie cup is a bonus for on the go breakfasts. We have tried other blenders, without pleasing results. Do not hesitate, this blender is a tremendous product at a great price!
