When comparing the Bella Rocket Blender 12-Piece Set and the OBERLY Portable Blender, there are some significant differences to consider.

On one hand, the Bella is a traditional, corded blender that can blend nuts, dried food, and frozen fruits but has difficulty with leafy greens and ice. On the other hand, the OBERLY is a cordless personal blender that is marketed for its take-along design, but its performance is subpar and often results in chunky consistency. 

While both blenders have their drawbacks, the Bella is the better choice if you prioritize blending performance over portability. Meanwhile, the OBERLY may win some fans for its mobility; still, its lackluster performance makes it less likely a practical alternative.

Protein Shake

0.0
  • Blending Time: 1 mins 30 seconds
  • Result: Smooth

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).

  • Blending Time: N/A
  • Result: Failed

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.

9.0

Frozen Fruit Smoothie

0.0
  • Blending Time: 1 min 10 seconds
  • Result: Silky Smooth
  • Suction:

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.

  • Blending Time: 2 mins
  • Result: Failed
  • Suction:

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.

0.0

Fibrous Greens

0.0
  • Blending Time: 20 seconds
  • Result: Failed

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.

  • Blending Time: 20 seconds
  • Result: Failed

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.

0.0

Crushed Ice

0.0
  • Ice Fineness: Coarse
  • Unblended Ice: 79% of 6 oz

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.

  • Ice Fineness: Coarse
  • Unblended Ice: 100% of 6 oz

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.

Build Quality

6.5

The motor’s build quality is on par with its price point, with a predominantly plastic housing reinforced by a thin metal layer on the outside. It doesn’t have any glaring flaws in finish, but we'd like things to be a bit sleeker, especially the outside. The same goes for the two blade assemblies. We're just less pleased with the blending cups since they both look less as quality, and feel more susceptible to damage.

The OBERLY feels a little cheap with low-quality materials. There’re a lot of hard plastic parts that are prone to scratching, from the motor base to the cup body. Even when we avoided using a scouring pad for cleaning, multiple little scratches annoyingly appeared on both the inner and outer surfaces. The blending cup became cloudy with use and the blade assembly, which looks flimsy and more thinning than most, comes substandard, too.

Blade

  • Type:
    Sharp and Dull Blades
  • Guard Material:
  • Blade Count:
    4
  • Removable:
    No
  • Dishwasher Safe:
    Yes

The set includes two blade assemblies: a cross blade and a flat blade. Both pieces have average quality and lack a refined appearance. The cross blade features four prongs, potentially resulting in faster and smoother blending of wet ingredients compared to two-pronged blades. The flat blade, also known as a dry blade, is specifically designed for grinding harder ingredients such as rice, coffee beans, and whole grains.

  • Material:
  • Type:
    Sharp and Serrated Blade
  • Guard Material:
  • Blade Count:
    6
  • Removable:
    No
  • Dishwasher Safe:
    No

The blade has six prongs: 4 are sharp and the others are serrated. Such a blade’s design is exclusive and showed prominence for heavier-duty tasks if the prongs were thicker, for the least. Unlike conventional personal blenders, the blade assembly is permanently attached to the motor base. This makes it more difficult to clean thoroughly, especially on the blade’s undersides.

Bella Rocket Blender Motor Base

OBERLY Portable Personal Blender Motor Base
  • Rated Voltage:

  • Weight:
  • Cord Length:
    2.3 ft (0.7 m)
  • Extra Feature:
    Silicone feet

The motor is relatively resistant to overheating compared to similar models, but only in case you avoid operating it continuously for more than one minute at a time. If additional blending time is required, you should allow the motor to cool for up to three minutes before starting the next 1-minute interval. Otherwise, a cooling fan alone won't be sufficient to prevent your blender from getting hot. 

Four rubber feet are placed underneath the motor to further enhance stability and reduce movement during operation. It also assists in providing proper ventilation for the motor.

  • Rated Voltage:
    N/A
  • Rated Power:
    175 Watts
  • Working Time:
    90 seconds
  • Protection:
    Yes
  • Weight:
    0.5 oz (14 g)
  • Cord Length:
    NaN" (NaN cm)
  • Extra Feature:
    Silicone feet

The 175-watt motor is certainly insufficient for solid ingredients. It has an idle blending time of 5 seconds and a maximum continuous runtime of 90 seconds per interval. If the idle time or the single working time runtime is exceeded, the blender will stop automatically, with the blue light switched off. These protection modes are considered necessary since without them your blender would get hot and become overloading, which then results in permanently damaged components. 

There are three silicone feet on the bottom meant to provide stability, but we found they didn’t help much in our testing. Our blender walked around on the counter anyway.

Blending Cup

5.0
  • Material:
    Plastic
  • Capacity:
    13.5 oz, 13.5 oz, and 6 oz
  • Weight:
  • Dishwasher Safe:
    Yes
  • Measurement:
    No
  • Suitable For:
    Small batches
  • Accessories:
    Two storage lid, two lip rings, two shaker Lid

This set includes three blending cups, two of which are 13.6 oz and one that is 6 oz. The two blending assemblies work interchangeably with all cups, making it very convenient to switch between different blending needs. The smaller cup is recommended for dry blends, as it comes with sieve lids that allow it to function as a shaker for ground spices and seasonings. There are also two storage lids and two removable lip rings included so you’ll find it easier to sip your drink straight from the tall cup.

  • Material:
    Plastic
  • Capacity:
    380 ml
  • Weight:
    1.0 oz (28 g)
  • Dishwasher Safe:
    Yes
  • Measurement:
    No
  • Suitable For:
    Small batches
  • Accessories:
    Lid, filter

The cup has 380ml (13 ounces) capacity and uses PC (polycarbonate) material. After rigorous testing, it was damaged in some areas, but so far, this hasn’t impaired the blender’s performance. The lid and filter are both made of PP (polypropylene). They’re designed to seal the cup nicely so we didn’t experience any leaking even when we shake the cup vigorously or turn it upside down. 

Note that when the blender is working, it is imperative to open the lid or put anything into the cup for optimal safety. Your machine will stop working when its cup is separated. However, since the cup is a hollow piece with dual openings, remember not to remove the cup from the motor base when liquid is still inside.

Hands-Free Operation

3.0

The BELLA personal blender boasts a convenient hands-free feature, which enables blending once the cup is locked in place, eliminating the need to continuously hold the cup and activate the motor. However, it may struggle with heavy-duty tasks as it can't draw ingredients towards the blade on its own. During the smoothie test, there were brief pauses every 20 seconds to shake the cup as the frozen fruits got stuck under the blade and caused jamming. This is a common issue among personal blenders and wouldn't pose a significant problem if one is willing to spend an extra minute or two in the kitchen. In fact, some other models tested required multiple shakes to achieve a smooth blend.

To blend, you only need to hit the power button rather than pressing and continuously holding it during the operation like you have to do with most traditional personal blenders. Despite this, we couldn’t get the full advantage of the hands-free operation feature since there was barely a time we could stop shaking the blending cup. Otherwise, clogged food would prevent the blade from turning.

9.0

Assembly

7.5

The BELLA is designed for easy assembly, with clear and concise instructions included. To put all the components together, just screw the blade assembly to the blending cup, insert it into the motor, and then make a quick clockwise turn to lock it in place for blending starting. Some people might find it’s a little bit frustrating to secure the blade assembly to the cup, but most of them would get the hang of it after a few tries.

Attaching the lid, the filter, and the cup together is a breeze. We recommend screwing the filter onto the top of the blending cup first, then tightening the lid afterward. 

To finish the assembly process, just fasten the open end of the blending cup to the motor body so that the arrow on the cup is lined up with the arrow on the base. This takes some getting used to, but will be easier to do after practice. In case the jar isn’t aligned with the base properly, your blender won’t run while the red and blue light flash alternatively. 

Parents with young kids will appreciate this locking function of the OBERLY. After several uses, however, it no longer works efficiently. Sometimes, we didn’t align the arrow on the cup to match the arrow on the base, but our blender was still able to blend.

Separating all the pieces is easier.  Simply do the reverse of the assembly process.

8.5

Cleanability

8.0

Except for the motor body, all the pieces are safe to put in the dishwasher, though we decided to clean them by hand and noticed that part of the cleaning process was performed with ease, as any remaining residues of the cups and lids are removed simply by wiping the surface with a damp soapy cloth. 

The blades, on the other hand, required more attention due to their intricate design and close proximity to the assembly’s surface. As such, we had to use a straw-cleaning brush so that all remnants of food or other substances can be removed entirely.

The lid, filter, and blending cup are top-rack dishwasher safe. It’s advised to wash them by hand with warm, soapy water,though, so they don’t degrade as quickly. The motor body shouldn’t be immersed in water so we cleaned its exterior surface with a soft cloth and then scrubbed away food tailing in the blade assembly with a bottle-cleaning brush. So far, we haven’t have any trouble in doing this, but for those with large hands, cleaning the blade’s undersides may become a little bit trickier, especially when there isn’t a brush available.
