Bella Rocket Blender 12-Piece Set vs. Ninja Nutri Auto-iQ Side-by-Side Comparison

In this test, the BELLA blender produced a nearly perfect protein shake in one minute and thirty seconds. There was a small smattering of partially intact berries and almonds found after straining, but the oatmeal was mostly blended well so this didn’t detract much from the overall quality of the drink. With a little bit of tweaking by letting it blend longer or soak the nuts prior to use, we would even get a chunk-free consistency. You’ll find lots of personal blenders in this class, but rarely of them might provide as smooth and quick results. Some took up to four minutes to liquify oatmeal entirely, while others' blades were too weak to churn through such solid fruits (for example, the Magic Bullet, the La Reveuse, and the Icucina).

The Ninja Nutri is essentially a single-serve blender but refinements to its blades and motor’s power have brought it many advantages over the competition. 

You might notice the blade assembly looks like nothing else in the market. Design-wise, it is attention to detail with four sharp, sophisticated prongs. Beyonds spinning extremely speedy, the prongs are towards various sides to allow for more food contact at a time. And such combos did make our Ninja Nutri among the fastest blenders in this test, taking one minute and ten seconds to yield a serving of protein shake. Not to mention the 1000-watt motor which helped churn through ingredients like almonds, dried berries, oatmeal, with super ease. 

As efficient as it was, this blender still underperformed by a few seconds against two top competitors (the Ninja Fit and the NutriBullet), though. The texture it delivered also had room for improvement since while the oatmeal was completely broken down, small amounts of almonds and berries remained solid. Considering the price, we had wished for a chunky-free texture which was exactly similar to those we got from its counterparts. 

Overall, unless you’re really interested in its professional look and hi-tech features, there are some alternatives that can actually blend your drink better and do so at less than half the price.

The BELLA is a classic example of why a cheaper blender isn't always worse because its smoothie-making capability proved to be even on par with those of higher-powered models, namely the Nutri Ninja Auto-iQ. This can be attributed to several factors, including blade design, motor strength, and blending speed.

The sturdy blade spined relatively fast. Working with a 240-watt motor, it took only one minute and ten seconds to blend and mix all the ingredients together. A very quick blending time for this class of blender, this speed is crucial when it comes to blending frozen ingredients as it helps to preserve the ice-cream-like texture that people look for in frozen fruit smoothies. 

For the smoothie’s consistency, while there were still small bits of raspberry skin and strawberry seeds present, this is to be expected when blending ingredients of this nature. Overall, these small bits didn’t impair the smoothie’s quality at all.

The Nutri Ninja was excellent at this test. Again, its distinctly-designed blades and higher-powered motor were good things for a quick, even outcome. They allowed the blender to power through all the frozen mango, strawberries, raspberries, and blueberries to perfection in just over one minute. And we remember everything was very easy and simple here, which you will rarely experience with other weaker personal blenders. Just noting that the process was fifteen seconds slower than that of the NutriBullet, but this wasn’t a huge gap. You might be willing to wait a bit longer as long as you get good results. 

Initially, we intended to use the Auto-IQ Ultra Blend setting, but the testing trials then suggested us shifting to the regular one. When running on the Auto-IQ Ultra Blend mode, your blender will blend in short intervals in 60 seconds and there will be a unique pulsing and pausing pattern after each interval. This is meant to force all the clogged ingredients back down onto the blades to even out the blend. That being said, we don’t think this is highly necessary in making icy smoothies; frozen fruits need to blend as fast as possible, but the pausing intervals give them time to thaw and then dilute the consistency. Perhaps, the Auto-IQ technology is better for dry-grinding harder ingredients like whole ice cubes and raw nuts.

Upon conducting a 20-second blending cycle, we found the BELLA couldn’t perform up to its usual standards being somewhat suboptimal in processing high-fiber foods, including kale, celery, and spinach. Strain analysis of the mixture revealed a substantial volume of greens remaining partially unblended which led to a grainy texture and an inadequate extraction of the green’s nutrients, in the end. 

On the contrary, some other blenders, like the Ninja Fit and the Ninja BN401, produced a smoother outcome with a significantly smaller volume of visible flakes. As such, our conclusion is that your BELLA is not well equipped to handle high-fiber foods and may fall short of the desired performance criteria for such applications.

The blender’s ability to process leafy vegetables was above average. The final drink came out acceptably uniform but with a gritty texture. We don’t think you’ll get too many complaints if you run everything through a mesh strainer before drinking. Given its high-end price tag, however, we expected better results with fewer leafy chunks.

The BELLA appeared to lack the necessary strength for such a tough application. As a result, all the ice cubes remained virtually intact despite its significant effort. To be fair, though, this is a common limitation among personal blenders. Should you desire crushed ice with a fluffy, snow-like consistency or intend to incorporate more ice into your smoothies, consider the NutriBullet or anything with at least a 700-watt motor.

As a personal blender, this Nutri Ninja didn’t perform half bad, grinding 6 oz of whole ice cubes in just 22 seconds. None of the other blenders we tested could do the same; some took longer to entirely break up the ice while others were simply not powerful enough to churn through such a solid ingredient. (For example, the KOIOS Pro and the Oster)The crushed ice didn’t have a snow-like texture, but would be good enough for your cocktails.
