The Ninja Fit QB3001SS wins because its 700-watt motor crushes ice and frozen fruit faster than the 600-watt Nutribullet. In our testing, the Ninja blended a kale and frozen mango smoothie completely smooth in 45 seconds, whereas the Nutribullet left noticeable chunks. Both cost exactly $57.99.
After using both machines for a week with identical recipes, we saw exactly how their motors handle daily abuse. Here is what happens when you load them with solid ice and fibrous greens.

Nutribullet Personal Blender (600W)
nutribullet Personal Blender NBR-0601WM
I tested the original Nutribullet by making daily protein shakes. The push-and-twist activation feels natural, locking the cup into the base so you can step away for a few seconds. In my testing, its 600-watt motor handled soft fruits and liquid-heavy protein shakes easily. However, when I loaded it with a cup of solid frozen strawberries, the blades stalled, requiring me to un-twist the cup, shake the ingredients loose, and restart the cycle.
Pros
- Locks into base for hands-free blending
- Blades twist off smoothly for fast rinsing
- Handles fresh fruit and protein powder without stalling
Cons
- 600-watt motor struggles with hard frozen fruit
- Requires manual shaking to dislodge ice blocks
- Lacks a travel spout lid out of the box
Verdict
The Nutribullet is a solid choice for liquid-heavy protein shakes and soft fruits, but its 600-watt motor struggles with hard frozen ingredients.
Ninja Fit Compact Personal Blender QB3001SS
The Ninja Fit operates through a push-to-blend mechanism—meaning you have to physically hold the cup down to run the 700-watt motor. I found this slightly annoying for longer recipes, but the motor tears through ingredients so fast you rarely hold it longer than a minute. In my testing, it pulverized a cup of solid ice into snow in 20 seconds, directly outperforming the Nutribullet on tough ingredients. The included 16-ounce cups with spout lids also made grabbing my drink on the way out the door much simpler.
Pros
- 700-watt motor aggressively crushes solid ice
- Pulverizes solid ice into snow in 20 seconds
- Includes 16-ounce cups with tight-sealing spout lids
Cons
- Push-to-blend mechanism requires physically holding the cup down
Verdict
The Ninja Fit is our top recommendation because its 700-watt motor quickly crushes solid ice and frozen fruit for smooth daily blending.
Motor Power
In our testing, motor wattage dictates how well a blender handles hard ingredients. A 700-watt motor crushes solid ice into snow in 20 seconds. A 600-watt motor struggles with frozen fruit and stalls, requiring manual shaking to dislodge blocks.
Activation Mechanism
Personal blenders operate differently. Push-and-twist models lock the cup into the base for hands-free blending. Push-to-blend models require you to physically hold the cup down while the motor runs, which can be annoying for longer recipes.
Included Accessories
Check the included cups and lids. Models that include 16-ounce cups with travel spout lids make taking your drink on the go much simpler compared to those lacking travel lids out of the box.
Conclusion
The Ninja Fit QB3001SS wins for its superior ice-crushing power. Buy the Ninja Fit if you blend frozen ingredients daily. Choose the Nutribullet only if you mix soft fruits and protein powder.
