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
Vitamix offers a high-powered single-serve blender that is more compact than the traditional Vitamix line. The model offers a 5-year warranty, very powerful motor, variable speeds, and is backed by Vitamix quality. Stronger than Nutribullet single-serve blenders but more expensive.
