The catch
Vitamix Explorian E310
There are no automatic food programs.
Side by side
The E310 is built around a manual 48-ounce pitcher. In the Ninja TWISTi, some pitcher volume is traded for a built-in twisting tamper, automatic functions and two cups.
Before you buy
A recipe too large for the smaller Power Pitcher is where E310's nominal pitcher volume, about 41% more than TWISTi, helps.
Where this comes from
Nominal increase: 14 / 34 × 100 = 41.2%, where 48 - 34 = 14 ounces.
The catch
There are no automatic food programs.
The catch
A family round of frozen drinks won’t fit in the 34-ounce pitcher.

A 48-ounce manual pitcher is the E310’s approach. Ninja TWISTi gives up some pitcher volume in exchange for a built-in twisting tamper, automatic functions and two cups.
A traditional tamper with a medium pitcher, or a twisting lid with travel cups
Which one fits
Separate drinks should be prepared within each vessel's own fill limit. Ninja supplies an eighteen-ounce cup and a twenty-four-ounce cup.
More main-vessel volume belongs to E310.
TWISTi’s pitcher includes that mechanism.
Variable speed and pulse are what E310 builds its controls around.
In practice
A recipe too large for the smaller Power Pitcher is where E310's nominal pitcher volume, about 41% more than TWISTi, helps.
Nominal increase: 14 / 34 × 100 = 41.2%, where 48 - 34 = 14 ounces.
Although one cup is six ounces smaller than the other, TWISTi can prepare two differently flavored drinks in separate supplied cups.
E310 lists one 48-ounce container and mini tamper. Ninja supplies one 18-ounce cup and one 24-ounce cup.
E310 keeps the familiar separate-tamper action, while the twist-lid mechanism suits users who want ingredient movement built into the lid.
A removable mini tamper comes with E310, and a built-in twisting tamper is documented for TWISTi.

Vitamix, E310 Black

Ninja, SS151

Decision guide
Pick between the E310’s 48-ounce manual pitcher and the TWISTi’s built-in twisting tamper, automatic functions and two cups, which come at the cost of some pitcher volume.
Through the lid opening, you push a removable mini tamper on the E310. The TWISTi builds its twisting tamper into the lid of its Power Pitcher. Decide which motion you would rather use when dense recipes need managing.
A 34-ounce pitcher, an 18-ounce cup and a 24-ounce cup all come with the TWISTi, while the E310 has one 48-ounce jar. Two commuters can make separate drinks, though the smaller Ninja cup can’t hold the same nominal portion as the larger one.
Speed and stopping are yours to control on the E310. The TWISTi has five Auto-iQ functions. Without a comparable test, neither nominal motor rating tells you which makes the better smoothie bowl.
