What you give up
Recommendation switch
Choose Ninja TWISTi High-Speed Blender DUO. Ninja supplies two personal cups, sized eighteen and twenty-four ounces, for separate drinks.
Choose Vitamix Explorian E310. E310 has more main-vessel volume.
Choose Ninja TWISTi High-Speed Blender DUO. That mechanism is part of TWISTi’s pitcher.
Choose Vitamix Explorian E310. E310 centers its controls on variable speed and pulse.
What matters in practice
E310 uses a removable mini tamper through its lid opening. TWISTi builds the twisting tamper into its Power Pitcher lid. Choose the action you want to perform while managing dense recipes.
TWISTi combines a 34-ounce pitcher with an 18-ounce cup and a 24-ounce cup. E310 provides one 48-ounce jar. Two commuters can prepare separate drinks, but the smaller Ninja cup cannot hold the same nominal portion as the larger one.
E310 puts speed and stopping in your hands. TWISTi offers five Auto-iQ functions. Neither nominal motor rating can establish which produces the better smoothie bowl without a comparable test.
