Ninja QB3001SS Fit vs NutriBullet 900-Watt Pro Side-by-Side Comparison

No matter what ingredients you have on hand for your protein shakes, the Ninja QB3001SS Fit will quickly turn them into a chunk-free mix. Its impeccable performance in this test is evidence of that. Consisting of the toughest-to-blend ingredients, our recipe presents a high level of difficulty, but it still didn’t give this blender any trouble. 

Our Ninja took only 50 seconds to churn out the desired result. The oatmeal was completely broken down while almonds and berries were blended to their finest state. After straining the drink through a strainer, we found a smattering of partially blended chunks, but we don’t think it's enough to turn off many folks. Given such a result, this machine is a worthy competitor to the NutriBullet Pro — our best personal blender at the time of writing.

The NutriBullet Pro is amazingly capable when it comes to preparing protein shakes. In this test, it was the fastest contender, mixing a silky-smooth workout drink in only 40 seconds. It blended well enough that we didn't need to shake the cup to promote contact between the food and blades. The blade spined extremely fast and together with the mighty motor, it allowed the blender to draw everything toward the blades and tear apart each at the same time without any struggle. You might notice there even wasn’t a time that food clinged to the sides of the cup.

There were also blenders that delivered the same result, such as the Ninja Fit, but they all demanded extra shaking or stirring to dislodge chunks trapped on or around the blades during the blending process. Efficiency aside, it’s apparent that your NutriBullet Pro will also outperform its rivals in terms of use ease.

When it comes to preparing smoothies, this blender’s efficiency is something that we’ve all dreamed about, but never thought possible on a budget. In our test, it allowed for a quick preparation of frozen foods with very little effort thanks to its heavy-duty motor and sturdy blades. The compromise was that we had to pause now and then to shake chunks free from the blades.  

The smoothie was ready to drink within 1 minute of blending, which was far faster than average. In fact, it was fully twice as fast as some other models like the Magic Bullet, the Hamilton Beach, and the Oster. You may think it doesn’t matter much to wait a bit longer, but actually, the difference in blending time between blenders did create a substantial discrepancy in the drink’s texture and temperature.

As a general rule of thumb, frozen foods thaw quickly at room temperature, especially when you start grinding them up. The faster your blender does its job, the thicker and less diluted your smoothie will be. 

Simply put, not only did the Ninja Fit blend smoothly, but its rapid operation also provided us with the thick, ice-cream-like consistency that we prefer in frozen fruit smoothies. If you’re craving icy-cold drinks on hot days, this blender definitely has the chops for it.

The NutriBullet completed our smoothie in less than a minute, and its results were unparalleled. Our smoothie came out exceptionally velvety. Although there were still tiny flecks of raspberry skin and strawberry seeds, this is a common occurrence when it comes to processing such ingredients. 

It’s worth noting here that no other personal blender we tested could produce such an ideal texture in the same time frame; some couldn’t even break down strawberries after a full minute. Again, this blender never demanded that we shake the cup or stir the contents, and we really couldn't be happier.

Aside from the high-speed rotation and powerful motor, we supposed the blade assembly is a factor creating this outstanding performance. Personal blenders typically feature a blade assembly with two or four prongs, but the NutriBullet is an exception. Made of first-grade stainless steel, its blade is a clear step above those of the competition, including even the pricey Ninja Nutri Pro. It isn’t super sharp, but looks thicker than most and has up to six prongs. More prongs allows for more food contact at the time so the final drink will come out faster and finer.

The Ninja Fit is quite capable of incorporating leafy vegetables and other fiber-filled foods into your drink. Of all the blenders we tested, this was one of the few that could break down almost all of kale, spinach, and celery in only 20 seconds. The greens were blended finely and had consistent-sized grounds. Not only that, but it left us with only a little pulp that was too big to pass through a strainer — better results than even the pricier Nutri Ninja Auto-IQ.

Liquifying high-fiber whole food like leafy veggies is always a challenging task for personal blenders, but the NutriBullet’s performance really made it stand out from the rest. 

It could break all the ingredients down into their finest state in only 20 seconds. We drained the completed drink through a mesh strainer and noticed it left behind very few leafy chunks. It could produce an even better result if we blended longer. 

Actually, we didn’t expect such good results so quickly. Most of the machines we tested turned out very coarse blends on this test, such as the Magic Bullet.

In this task, this blender struggled quite a bit, and couldn’t quite power through all the ice cubes. A small amount of ice remained solid — accounting for 20% of the total — when it was all said and done. And again, we had to stop and shake the blending jar to promote the contact between the ice and blades. 

Of all the blenders with small blending cups, however, the Ninja Fit was the only one that actually could perform that well. It even crushed ice as fluffily as its larger counterpart, the NutriBullet Pro. With the Ninja Fit, you may no longer have to deal with whole ice cubes in your drink.

The NutriBullet Pro is not only capable of crushing ice cubes, it excels at it! We tested a myriad of personal blenders, and so far haven't found a single machine that can crush ice as fluffy as this one. 

It finished the test in about 40 seconds. A couple of ice chunks still remained solid, but it didn’t look like the blades would be able to grab them. Nevertheless, this NutriBullet performed wonderfully and is very deserving of the top score.
