Ninja Fit vs nutribullet 600: Which Personal Blender Should You Buy?
Short answer: The Ninja Fit, for most people. It has more power, two cups and a far better durability record. Get the nutribullet if you want one bigger 24 oz cup.
Ninja Fit
4.7★ · 42,333 ratings
- You blend frozen fruit or ice most mornings
- You want two cups, so one can sit in the dishwasher
- Durability worries you more than cup size
nutribullet 600
4.6★ · 50,062 ratings
- Your smoothie is a full meal and needs a 24 oz cup
- You mostly blend fresh fruit, greens and protein powder
- You want the simplest press-and-twist design
These two sit at #1 and #3 in Amazon’s personal blender rankings. They look like the same appliance in different colors, a motor base with an upside-down cup, and they’re priced close enough that the choice often comes down to which brand you’ve heard of. The numbers suggest a clearer answer.

The deciding difference: how long it lasts
Both blend a good smoothie. That part is close. Where they split is durability, and the gap is wide.
For the Ninja Fit, 256 of 522 durability mentions are negative, about 49%. That’s not great, but it’s the best record among the personal blenders we looked at. For the nutribullet, 674 of 788 durability mentions are negative. That’s 86%, with several owners describing a base that quit after a month or two. A gap that size, across hundreds of owners on each side, is hard to explain away.
Where they differ
Cup size. This is the nutribullet’s real advantage. One 24 oz cup holds a breakfast-sized smoothie with room for ice. The Fit’s 16 oz cups fill up fast, and 201 of its 661 size mentions are complaints, mostly from owners who wish the cups were bigger.
Ice and frozen fruit. ShouldIt ran the Fit through its personal-blender tests. It made a silky frozen-fruit smoothie in 1 minute and a protein shake in 50 seconds, and it ground ice very fine with about 20% left whole. Testers also measured 98 dB and noted that it needed a few shakes for an even blend. We couldn’t find an equivalent lab test of the 600, so for it we’re leaning on owners. They’re delighted with smoothies, 352 of 360 positive, but those reviews are mostly about fruit, greens and shakes rather than ice.
Daily use. The Fit runs only while you hold the cup down, which is a bit tedious for a 60-second blend. The nutribullet uses a push and twist. Owners notice the difference: 90% of the Fit’s 1,192 ease-of-use mentions are positive, against 68% of the nutribullet’s 693.
What owners say
Ninja Fit owners talk most about speed and power, at 94% positive for each. Several mention needing only three or four pulses for frozen berries.
nutribullet owners love the smoothie texture and how fast cleanup is, at 93% positive. The complaint is the same one repeated hundreds of times: it stops working too soon.
Our pick
Buy the Ninja Fit. It’s lighter, a bit stronger, comes with two cups, and gives you better odds of a second year. Choose the nutribullet 600 only if one 24 oz cup really matters to you, and keep the receipt.

FAQ
Is the Ninja Fit more powerful than the nutribullet?
On paper, yes: 700 W against 600 W. Oddly, the nutribullet listing's own spec table says 700 W, while its title and bullets say 600 W. Owners rate both highly on power and blending, so the gap matters most with ice and hard frozen fruit.
Can either one crush ice?
Ninja markets the Fit for crushing ice and frozen ingredients, and ShouldIt's testers found it crushed ice very fine, with about 20% of the cubes left whole. nutribullet's listing talks about fruits and vegetables, not ice, so add liquid and don't expect slush from the 600.
Which is easier to clean?
Both are top-rack dishwasher safe and rinse clean in seconds. Owners give cleaning about the same marks: 89% positive for the Fit and 93% for the nutribullet.
Do they need you to hold the cup down?
The Ninja Fit runs only while you press the cup down. The nutribullet's listing describes a push-and-twist action instead, so you don't have to keep pressing for the whole blend.
