I bought this blender after some research into different personal blenders on the market. My previous bullet-style blender did not have enough cup capacity and wattage to get the job done. I would constantly find the motor would get too hot and short out. This blender has plenty of power to get through anything! I also love it has different size cups but they all fit the same blender blade base. Auto-IQ is an amazing function and has taken ALL guesswork out of blending drinks.
