The Ninja BL480D Nutri is a reliable option for improving your daily meal with more nutrition-extracted foods. In our tests, it made protein shake, extracted leafy greens, and liquefied frozen fruit far better than most of its rivals, including the Oster BLSTPB-WBL. It was even powerful enough to provide us with  snow-like crushed ice. 

The trade-off is its hefty bulky weight, which ruins the overall portability that a personal blender should provide. Additionally, while we appreciate the idea of  intelligent programs, they are just an exchange for the premium price and  please no one, if not on the gimmicky side. 

The Oster BLSTPB-WBL, by contrast, is an average single-serve blender with a compact, sporty design. It feels light but not flimsy, and although it isn’t as heavy-duty as its higher-powered peer, it worked constantly, churning out products that were better than many of its rivals in this price range. 

In short, if you don’t want to buy a personal blender that may cost you a fortune and are only focused on simple blends, the Oster BLSTPB-WBL is an adequate choice.

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

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.

Using a spoon to scoop a small smattering of dried blueberry chunks from a mesh strainer containing protein shake produced the Oster Single-Serving Blender.
  • 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.

  • Blending Time: 1 min 5 seconds
  • Result: Silky Smooth
  • Suction:

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.

  • 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.

  • Blending Time: 20 seconds
  • Result: Fine

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.

  • 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.

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.

  • 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 Ninja Nutri is larger and bulkier than your average single-serve blender. The motor section looks more like a full-sized countertop version, coming in at 14.5 inches tall by 6.2 inches wide. At 5.4 pounds, it’s also heavier than most, so you may find it difficult to move your blender in and out of storage.

Build Quality

7.0

Build quality does match the price point. It’s good, with many parts — to include the entire exterior — made of anti-scratch plastic. We haven’t had to deal with problems like discoloration, paint peeling, or inner components wearing out. Additionally, the construction is sturdy enough to hold up frequent use, so you will get stable performance and consistency for many years.

The motor base and blending cup with blade assembly attached of the Oster single-serve blender.

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.

The motor comes with many user-friendly components. They include a cooling fan to prevent overheating, suction feet to help the blender stand firm against heavy-duty tasks, and small anti-slip pads to minimize the risk of sliding on wet surfaces. We’re also impressed with the inner parts which are all well-made and detailed. 

Just be aware that the motor should not run for more than one minute continuously. If your recipes demand longer than this timeframe, blending for 1-minute intervals can help you avoid overheating. In the event your machine gets too hot, a built-in thermal switch will engage and stop the motor from running. To reset, you’ll have to unplug and let it cool down for 30 minutes before blending again.

  • 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.

The front interface is intuitive, featuring four buttons that correspond to four different options. As a visual aid, this model also has a digital display which indicates the elapsed blending time or counts down to the end of a preset program. 

If you want continuous blending, press the Start/Stop button. To avoid chopping ingredients too finely, use the Pulse function. For fresh or softer ingredients, the Auto-IQ Blend button will help you create consistent results without relying on guesswork. There is also the Auto-IQ Ultra Blend button, which runs the blender at its fastest speed tobreak ice cubes, fibrous greens, whole grains, or frozen mixtures down to a lump-free consistency. 

We found that the speed settings work very well. Each step gives you a noticeable change in power level. For the most part, however, we agree with some reviewers that it feels a bit gimmicky because single-speed blenders generally work just as well.

Note that regardless of the speed setting, this Nutri Ninja is terribly noisy. If noise is a major factor in your buying decision, this one’s not for you.

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

6.5

This blender is more convenient to use than others because the cup can be locked in place; you won’t need to hold the cup continuously to engage the motor. Additionally, once activated, it draws almost everything toward its blades, creating a homogeneous mixture without extra shaking or stirring.

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.

9.5

Assembly

7.5

To set up the blender, simply attach the extractor blade to the cup, turn the whole assembly upside down, and place it on the motor base. Once the display reads “0,” press one of the buttons to start blending. When your drink is complete, simply pull the cup out from the motor base and serve. Note that you must pull with quite a bit of force compared to other blenders we tested, so it may be tougher to remove when your hands are wet or oily.

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

8.0

We cleaned the cups, lids, and blade manually with soapy water, but they’re also safe to put in the dishwasher. Of all those parts, the blade’s backsides were the trickiest to clean, so make sure you have a straw-cleaning brush available. 

The motor base only took us a couple of minutes to wipe down. Unplug the device and use a dish cloth dampened (but not soaked) with soapy water to wipe down exterior surfaces and the inside of the cup receptacle. We never had any leakage during our tests, so we didn’t have to contend with stubborn food on the actuator tabs or other components.

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.
