Blendtec is a high-tech, high-powered blender line that is perfect for all your smoothie needs. You can just push the "Smoothie" button and the Blentec blender will do the rest while you are busy doing other things. A high quality option with lots of functionality.
Ninja has a large range of blender models. The look is similar to Blendtec and Vitamix with a large pitcher and wide base but Ninja blenders are lower priced. Overall a good blender if you don't have the budget for higher-end Vitamix or Blendtec. Read our detailed Ninja Buying guide
