Ninja BN701 Review: Ice in 20 Seconds, Kale in Three Minutes and Still Chunky

Shouldit scored crushed ice a perfect 10 and a regular green smoothie 4.6. The blade stack that makes the first result possible is what causes the second.

Ninja Professional Plus Blender with Auto-iQ

Fair · researched from 3 sources

A superb ice crusher and frozen drink machine wrapped around a blade design that fights you on anything fibrous. If your blender's job is smoothies from frozen fruit and margaritas, this is very good value and very loud.

Ten out of ten, and 4.6 out of ten

Shouldit scored crushed ice a perfect 10, at 20 seconds to a very fine texture.

Shouldit scored a regular smoothie 4.6, after three minutes, still chunky, with strips of leaf left in it.

Same blender, same afternoon. The gap between those two numbers is the entire review.

The reason is the blade stack

Shouldit's explanation is the most useful thing written about this machine: the stacked blade assembly does not efficiently draw ingredients down toward the blades, and centrifugal force pushes the contents outward rather than into the centre.

For ice, that does not matter. Ice is heavy and falls back into the blades under its own weight, which is why six blades stacked at different heights shred it so effectively.

For kale, it matters completely. A leaf is light, it goes outward, and it stays plastered to the wall of the pitcher while the blades spin in a hole in the middle.

Every source reports stopping to stir. That is why.

What the pattern looks like across three reviews

TechGearLab: smoothies 6.0 out of 10, excellent on berry and Oreo, struggling with green smoothies and fruit-and-oat blends. Frozen drinks 7.5, margarita in 120 seconds.

Shouldit: frozen fruit smoothie 6.5 after four minutes, silky but needing manual intervention. Protein shake 7.6. Almond butter 7.8 after five minutes. Regular smoothie 4.6.

Blender Junkie: frozen fruit smoothies perfectly smooth in about 20 seconds.

Frozen and heavy: good. Fibrous and light: not good. There is no source that disagrees with that split.

And it is extremely loud

Shouldit measured 99.3 dB and compares it to a vacuum cleaner.

Blender Junkie's version is the one you will remember: pause-your-conversation loud, wake-the-dead loud.

TechGearLab lists it among the criticisms without a number.

The things it cannot do at all

TechGearLab tested soup and got a grainy, lumpy texture, and points out the machine cannot heat while pureeing, so it fails as a soup blender twice over.

It cannot grind kernels into flour.

And Shouldit found two build problems worth knowing: the plastic pitcher scratches easily after very little use, and the blade assembly can misalign with the lid in a way that risks damaging both.

Against all of that, a 72-ounce pitcher, three clearly labelled presets that TechGearLab scored 8.0 out of 10, and everything except the base going in the dishwasher, at a price both TechGearLab and Blender Junkie call good value.

How it scored

The overall 6.5 is the weighted average of these five criteria — we never adjust it by hand.

Performance

25% of score6.5

Shouldit scored crushed ice 10 out of 10 at 20 seconds and a regular smoothie 4.6. TechGearLab scored smoothies 6.0 and pureeing 5.8, calling soup grainy and lumpy.

Value

25% of score8.0

TechGearLab ranked it tenth of fifteen at 68 out of 100 and calls it affordable. Blender Junkie calls it exceptional value. Shouldit scored 6.5 out of 10.

Build quality

17% of score6.5

Six stacked stainless blades at varying heights in a 72 oz plastic pitcher. Shouldit reports the plastic scratching easily and a blade-to-lid misalignment risk.

Ease of use

17% of score8.0

TechGearLab scored controls 8.0 out of 10 with three clearly labelled presets, and cleaning 7.9. Blender Junkie notes everything but the base is dishwasher safe.

Noise

17% of score3.0

Shouldit measured 99.3 dB, which they compare to a vacuum cleaner. Blender Junkie describes it as pause-your-conversation loud. TechGearLab lists noise as a criticism.

How we researched this

We have not had this unit on the bench. This review synthesises the manufacturer’s published specifications, independent measurements and owner reports listed below. Every figure on this page comes from one of those sources rather than our own measurement.

3

sources reviewed

TechGearLab tested it against fourteen other blenders and supplies the category scores and weights, the timed frozen drink and ice results, the soup and flour findings and the motor rating, ranking it tenth of fifteen at 68 out of 100. Shouldit supplies timed and scored results for five separate tasks, the measured noise level, the blade count and geometry, the weight and dimensions and the mechanical explanation for the leafy green failure, scoring 6.5 out of 10. Blender Junkie supplies the liquid capacity, a third smoothie observation, the dishwasher detail and practical criticisms about storage and the suction feet. The motor is given as 1200 W by one source and 1400 peak watts by two, which is most likely continuous against peak, and both are reported.

Common questions

How well does the Ninja BN701 crush ice?
Better than anything else it does. Shouldit timed 20 seconds to a very fine texture and scored it a perfect 10 out of 10, their highest score for any task on this blender. TechGearLab took 60 seconds to reach what they call a soft, uniform powder and scored frozen drinks 7.5 out of 10, their strongest category, adding that a margarita reached the right texture in 120 seconds. Blender Junkie found the ice handled without hesitation. Three sources, one conclusion.
Can it make a green smoothie?
Not well, and the sources split in a way that resolves cleanly. Shouldit scored a regular smoothie 4.6 out of 10 after three minutes, describing a chunky result with significant strips of leaf remaining. TechGearLab scored smoothies 6.0 out of 10, excellent on berry and Oreo varieties and struggling with green smoothies and fruit-and-oat blends. Blender Junkie got perfectly smooth results in about 20 seconds, from frozen fruit. Frozen fruit works. Fibrous leaves do not. Shouldit's frozen fruit smoothie scored 6.5 while their green one scored 4.6, which is the same pattern inside a single review.
Why does it struggle with leafy greens?
Shouldit gives the mechanical explanation, and it is the most useful sentence anyone wrote about this blender. The stacked blade assembly does not efficiently draw ingredients down toward the blades, and centrifugal force pushes contents away from the centre rather than into it. That is the same geometry that makes it excellent at ice, where the pieces are heavy and fall back into the blades on their own, and poor at leaves, which are light and end up plastered to the pitcher wall. It is why every source reports needing to stop and stir.
How loud is it?
Very. Shouldit measured 99.3 dB and compares it to a vacuum cleaner. Blender Junkie's description is more useful in a kitchen: pause-your-conversation loud, and wake-the-dead loud. TechGearLab simply lists noise among the criticisms. For reference, sustained exposure above 85 dB is where hearing protection starts being recommended, though nobody runs a blender for hours.
What else does it not do?
Three things TechGearLab tested and found wanting. Soup comes out grainy and lumpy, and the machine cannot heat while pureeing, so it is not a soup blender in either sense. Nut grinding is subpar and needs repeated manual mixing, though Shouldit did get an acceptable almond butter after five minutes and scored it 7.8. And it cannot grind kernels into flour at all. Shouldit adds two build notes: the plastic pitcher scratches easily after minimal use, and the blades can misalign with the lid in a way that risks damage.

The bottom line on the Ninja Professional Plus Blender with Auto-iQ

A superb ice crusher and frozen drink machine wrapped around a blade design that fights you on anything fibrous. If your blender's job is smoothies from frozen fruit and margaritas, this is very good value and very loud.

The temperature control is as good as any lab has measured on a domestic circulator. The one thing everybody complains about is a timer that starts before you put the food in.

One lab ranked it first of eleven and gave its interface a perfect ten. It also measured the temperature running five degrees hot, which matters more for baking than for anything else it does.

It is not rated for pressure canning low-acid food, which is the one thing worth knowing before you trust it with anything. Everything else it does well enough to replace four appliances.
