Bella Rocket Blender 12-Piece Set vs Oster My Blend Side-by-Side Comparison




Our Verdict
- Performance (60%)5.7/10
- Design (25%)7.8/10
- Usability (15%)8.7/10
- Performance (60%)3.9/10
- Design (25%)6.6/10
- Usability (15%)7.0/10
The BELLA Rocket was well capable of producing smooth protein shakes in our tests. There were a small number of partially intact berries and almonds after straining, but we thought those could add a delightful textural element. The blade design, motor strength, and blending speed of the BELLA allowed it to create quick and smooth smoothies, as well.
The Oster My Blend is also a competent machine for the price, but compared with the BELLA, it lacks the finesse and speed of the BELLA. When it came to processing denser foods, however, both blenders couldn’t be up to the tasks, resulting in somewhat inadequate mixtures.
The overall design of the two products also varies considerably, with the BELLA being functional but unremarkable in terms of aesthetics. In contrast, the Oster blender places a greater emphasis on style and design, making it a preferred choice for consumers seeking a more premium-looking unit.
In summary, the Oster blender is the better option for consumers who prioritize design and aesthetics. However, for those who value efficiency and practicality, the BELLA blender provides better bang for the buck, particularly given its range of practical accessories.

Protein Shake
- 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: 2 mins 50 seconds
- Result: Coarse
The consistency of the Oster’s protein shake was about average and much in line with other low-powered blenders, such as the Black+Decker FusionBlade. After letting it pass through a mesh strainer, we found a small amount of dried berries remaining partially intact and this made the shake somewhat gritty. The oatmeal and almonds were mostly turned into liquid form, however. So overall, the beverage was still drinkable enough to help an athlete or gym enthusiast increase their muscle mass without feeling uncomfortable.
Despite being second to none within its market segment, this blender abjectly surrendered to its higher-priced counterparts in terms of blending time. To manage an acceptable result, it took up to nearly three minutes, which was about one minute slower on average. For this reason, we only gave it a 5.2/10, in comparison to other personal blenders in our Protein Shake test.
Frozen Fruit Smoothie
- 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: 1 min 40 seconds
- Result: Silky Smooth
- Suction:
The Oster BLSTPB-WBL did fairly well in this test, producing a result that was roughly the same as that of a higher-powered blender. So if you tend to focus on frozen smoothies, this device should be worth your consideration. Spinning at speed, we can assure you its blades will yield a silky frozen smoothie without a particularly intense struggle. Just make sure to give your blending cup a good shake once you notice any food getting stuck in the blades and prevent them from turning.
However, you might be wondering why it only got a 6/10 if its smoothie came out that good. Again, it was because of its longer-than-average blending time.
In particular, after a course of testing trials, we found that a good blender for making icy beverages has to process all the frozen ingredients as fast as possible so they don’t have time to thaw and dilute the overall consistency. As such, the completion time of the Oster meant its smoothie was thinner and less ice-cream-like than faster models, namely the Ninja Fit or the NutriBullet.
Fibrous Greens
- 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: Very Coarse
With the Oster, it was definitely an undertaking to extract high-fiber food into liquid form in a short period of time (20 seconds). By our cutoff point, we drained the final mixture with a mesh strainer and ended up with a substantial amount of coarse pulp. This suggested that the test was just one-third completed.
Perhaps, if we allowed this blender a longer runtime, we would eventually get a smoother outcome. However, one noticeable point was that some personal blenders we tested could do this trick perfectly following the same time frame. (For example, the Nutri Ninja Auto-IQ). As such, the performance of this Oster means more than just a slower extraction — it also has some implications for its overall efficiency in comparison with the expensive, high-end ones.
Crushed Ice
- 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: Chunky
- Unblended Ice: 65% of 6 oz
The weak motor power didn’t allow the Oster BLSTPB-WBL to crush ice so the final outcome came out almost pristine but this is a common occurrence of this type of personal blender. If you want fluffy, snow-like crushed ice or desire to incorporate ice into your smoothies, we recommend more powerful blenders, like the Ninja Fit.

The Oster BLSTPB-WBL is 5.5 inches wide and14.5 inches tall with the blending jar attached. It’s not so bulky, but a bit taller compared to most single-serve blenders. Despite that, we believe it would fit nicely in a tiny kitchen or easily tuck away in any cabinet when it’s not in use.
Build Quality
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 overall build quality is more than acceptable. The whole construction is made out of plastic, except for the blending blade, which is the standard in most budget-friendly personal blenders. We can’t say for sure if such a material makes this blender less durable than the ones reinforced with stainless steel, but it surely means that your machine isn’t as steady, resulting in the fact that it will be shaky when tackling heavy-duty blends.
Blade
- Material:Stainless Steel
- 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:Stainless Steel
- Type:Dull Blade
- Guard Material:
- Blade Count:4
- Removable:No
- Dishwasher Safe:Yes
The blade assembly looks solid, adding extra value to the overall product. That being said, it comes with dull prongs made of stainless steel, not sharp, which are typically more ideal for processing dry ingredients rather than wet mixtures.
Bella Rocket Blender Motor Base
- Rated Voltage:120V
- Rated Power:240 Watt
- Working Time:≤ 1 minute
- Protection:No
- 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:120 V
- Rated Power:250 Watts
- Working Time:N/A
- Protection:Yes
- Weight:2.2 lbs (1.0 kg)
- Cord Length:2.1 ft (0.6 m)
- Extra Feature:Handle
The motor peaks around 250 watts, which is sufficient to handle simple combinations of soft ingredients. In general, such a low-powered motor can only run continuously for one minute. Longer than that will result in an overloaded motor and cause it to be permanently damaged. More often than not, you can determine the maximum continuous runtime of your blender by checking its user manual.
So far, however, we haven’t found any information about the Oster’s motor in this regard. As such, it’s uncertain if this blender has a specific maximum runtime, especially when it’s packed with a built-in thermal resettable fuse to prevent damage in the case of extreme overload. Despite that, we still recommend not running it continuously for longer than 1 minute per interval.
Another nice extra feature that you won’t find in other blenders' motor bases is the handle, which gives it much better mobility.
Blending Cup
- 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:20 oz
- Weight:0.3 lbs (0.1 kg)
- Dishwasher Safe:Yes
- Measurement:No
- Suitable For:Small batches
- Accessories:To-go lid
Included in this set is a 20-oz blending cup with lid. We found the lid is easy to attach to the cup, but a little bit on the firm side to unscrew. It seals the cup so tightly that you can take your favorite beverages with you wherever you’ll go without leakage. You may also appreciate its flip-top spout, which allows you to take a sip straight from the cup easily and mess-free.
The cup, on the other hand, is not as practical. We like its beautiful and ergonomic design—which makes it feel good in our hands and ensures convenient handling—but there was always a problem getting our hands inside for cleaning due to its narrow structure.

Hands-Free Operation
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.
The Oster BLSTPB-WBL allows you to lock the blending cup in place so you won’t need to continuously press it down to the motor base for activation. However, this doesn’t mean that it will get the job done without your hands involved in the blending process. If your beverage is packed with tough ingredients which are too hard for the blade to power through, thus causing it to get jammed, sometimes you’ll need to stop the blender and give its cup a good shake to even out the blend.
Assembly
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.
There’s minimal assembly required since this blender has only three parts. First and foremost, you’ll need to fasten the blade assembly on the open end of the blending cup, then turn the whole piece upside down to place it in the base. For the proper result, make sure to line up the arrows on the blade assembly to the arrows on the base. Blending begins as soon as you press the cup down, but you can also lock the cup for hands-free operation by turning it clockwise in the base, though it can take quite some time to figure out how things work.
Cleanability
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.
All the parts, except for the motor base, are dishwasher safe, so simply add them to the top rack and you’ll have more time to spare for other activities. Hand washing is also nothing short of frustrating and worrisome. Make sure you have cleaning brushes handy for removing food tailings in the hard-to-reach spots of the long, narrow cup and the blade’s backsides.
