I was tired of the loudness and shifting around of my Vitamix 5200! I barely used it and it got hot quickly, so I sold it!! I am so happy that I purchased my Kitchenaid K400! It has many different modes!! I can make a drink 10 at night and not wake up ppl!!im so happy I brought this! Now I need the 16 oz personal carry container! I have to save up for that also!!! Im just happy that I beought this blender! Thank you Kitchenaid for a top of the line blender on a buget!!!!
