Bella Rocket Blender 12 Piece Set vs OBERLY Portable Blender 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 OBERLY is something very different, but not in a good way. Typically, personal blenders are designed for at least a serving of beverage. This OBERLY, however,  comes a little bit short on capacity. We were very surprised when our ingredients for the protein shake almost spilled out of the blending cup. The issues, however, didn’t just stop there, things got worse still when we started blending. 

Most other blenders we tested produced drinkable shakes in around two minutes. Whereas, the OBERLY couldn’t even have its blade spin since the nuts and dried berries were too solid to churn through. For the most part, they got clogged under the blade. Right after we gave the blender rigorous shakes, it did blend, weakly and in a very short interval. A few more shaking times didn’t help much, either. Finally, we had to admit that our OBERLY couldn’t be up to this test. So we allocated zero points to it.

If you already bought it, fear not: this blender is not a bad choice if your ideal of protein shakes just involves soft ingredients.

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.

We tested the OBERLY’s smoothie-making capability by blending and combining different types of frozen fruits together, but this seemed to be an overwhelming task for this blender. Everything happening here wasn’t much different from the protein shake test, except for the fact that with our repeated interference, the blender was able to blend on its own, with huge effort and time consumption, again. 

Every personal blender in this test has a limited operating time (2 minutes). Because of that, the OBERLY is considered to have failed this test since there were a lot of unblended chunks left behind when it already hit that runtime. Time constraint is necessary since frozen foods thaw quickly at room temperature; if you don’t blend fast enough, the smoothies will come out with a diluted texture rather than an ice-cream-like one. 

Nevertheless, if you can live with the compromises on smoothie’s texture and rations, this OBERLY is actually able to process certain frozen ingredients, churning out an icy beverage that may be acceptable enough.

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 OBERLY remained an underperformer in this test. It had a hard time liquefying our greens not only because of its weak motor power but also because its blending cup is too small to tackle such an amount of food (2.5 ounces). Most of the veggies didn’t circulate and made the blade stuck even when we undocked the cup and shook it rigorously. As mediocre as this blender was in the earlier tests, this failure wasn’t a surprise anymore, we admitted.

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.

Because of what we’ve been through with our blender, we shouldn’t expect much from it in this test. Gracefully, we did. To be fair, though, using a personal blender like this to crush ice is not a good idea; any heavy-duty task like this can take a toll on your device and impair its performance in more ordinary blends.
