To choose between the Oster BLSTPB-WBL and the NutriBullet 900-Watt Pro, you may need to determine what you need from a single-serve blender. If you simply need a solution for combining  soft ingredients, the Oster BLSTPB-WBL is not a bad choice. 

As a higher-powered blender, the NutriBullet 900-Watt Pro is particularly suitable for those requiring more on the heavy-blending performance side. The 900-Watt motor is more than sufficient to make the blender  a stand-alone ice crusher, so there were no surprises in  its peerless performance in our tests of making frozen fruit smoothies or protein shakes. 

However, you’ll need to consider your budget as well. While the Oster BLSTPB-WBL is a low-cost personal blender, the NutriBullet 900-Watt Pro is sold at a price that not everyone is able to afford.

Protein Shake

Oster BLSTPB-WBL Protein Shake
Oster BLSTPB-WBL Protein Shake 1
  • 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. 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. Overall, however, it was 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.

NutriBullet 900-Watt Pro Protein Shake
  • Blending Time: 40 seconds
  • Result: Silky Smooth

The NutriBullet Pro is amazingly capable when it comes to preparing protein shakes. In this test, it was the fastest contender, mixing a silky-smooth workout drink in only 40 seconds. It blended well enough that we didn't need to shake the cup to promote contact between the food and blades. The blender itself drew everything toward its blades very efficiently. There even wasn’t anything clinging to the sides of the cup.

6.0

Frozen Fruit Smoothie

10

  • Blending Time: 1 min 40 seconds
  • Result: Silky Smooth

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.

  • Blending Time: 50 seconds
  • Result: Silky Smooth

The NutriBullet completed our smoothie in less than a minute, and its results were unparalleled. Our smoothie came out exceptionally velvety. Although there were still tiny flecks of raspberry skin and strawberry seeds, this is a common occurrence when it comes to processing such ingredients. 

It’s worth noting here that no other personal blender we tested could produce such an ideal texture in the same time frame; some couldn’t even break down strawberries after a full minute. Again, this blender never demanded that we shake the cup or stir the contents, and we really couldn't be happier.

0.0

Fibrous Greens

9.0
Oster BLSTPB-WBL Fibrous Greens
  • 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. 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.

  • Blending Time: 20 seconds
  • Result: Fine

Liquifying high-fiber whole food like leafy veggies is always a challenging task for personal blenders, but the NutriBullet’s performance really made it stand out from the rest. 

It could break all the ingredients down into their finest state in only 20 seconds. We drained the completed drink through a mesh strainer and noticed it left behind very few leafy chunks. It could produce an even better result if we blended longer. 

Actually, we didn’t expect such good results so quickly. Most of the machines we tested turned out very coarse blends on this test.

0.0

Crushed Ice Cubes

10

  • 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.

NutriBullet 900-Watt Pro Crushed Ice Cubes
NutriBullet 900-Watt Pro Crushed Ice Cubes 1
  • Ice Fineness: Very Fine
  • Unblended Ice: 3% of 6 oz

The NutriBullet Pro is not only capable of crushing ice cubes, it excels at it! We tested a myriad of personal blenders, and so far haven't found a single machine that can crush ice as fluffy as this one. 

It finished the test in about 40 seconds. A couple of ice chunks still remained solid, but it didn’t look like the blades would be able to grab them. Nevertheless, this NutriBullet performed wonderfully and is very deserving of the top score.

  • Shaft Length:

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

9.5
Oster BLSTPB-WBL Build Quality

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.

NutriBullet 900-Watt Pro Build Quality

This blender has a flawless finish. Its build quality is better than most rivals. It is also more pleasing to the eye and neither the motor base nor the blending cups scratch easily. For the most part, after a careful inspection, we all agreed the NutriBullet Pro was a better product than it looked at first glance.

    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.

  • Removable:
    No
  • Dishwasher Safe:
    No

The blade is made of high-quality stainless steel and has 6 prongs. Solidly built, it is even more heavy-duty than it seems on paper. Still, the manufacturer recommends that it not be used for dry grinding or as a regular ice crusher since this may impair its efficiency and limit its lifespan.

Motor Base

  • 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
  • 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.

  • Rated Voltage:
    110 - 120 V
  • Rated Power:
    900 Watt
  • Working Time:
    ≤ 1 minute
  • Protection:
    No
  • Weight:
    3.7 lbs (1.7 kg)
  • Cord Length:
    2.5 ft
  • Extra Feature:
    Silicon feet

Peaking around 900 watts, the motor is powerful enough to handle just about any blending project. However, be aware that it cannot run longer than 1 minute at a stretch. If more time is needed, you should allow the motor to cool down for 20-30 seconds before continuing with the next 1-minute interval. This will help protect your machine from being permanently damaged. 

There are four silicone feet on the bottom of the base to keep it steady during operation. So far, ours hasn’t tried to bounce around on the counter even while tackling intensive tasks like crushing ice cubes. 

The rubber gasket built around the top is also very helpful. It’s meant to hold the cup tightly to the base, reducing the risk of leakage. On the other hand, we’re quite disappointed about the power cord. It is so short that it often got pulled from the outlet while we were using it.

Blending Cup

Oster My Blend Blending Cup
  • Material:

  • 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.

NutriBullet Pro 900W Blending Cup
  • Material:
    Plastic
  • Capacity:

  • Weight:

  • Dishwasher Safe:
    Yes
  • Measurement:
    No
  • Suitable For:
    Small and medium batches
  • Accessories:
    2 to-go lids, 2 cup rings, 2 handled rings

There are two identical blending cups with lids included. They both have a capacity of 32 oz and can be used interchangeably with the extractor blade. The to-go lids feature flip-top spouts and screw on tightly to seal well; we got no leakage even when we turned the cups upside-down. As a nice bonus, this blender also comes with removable lip rings, which make the cups easier to sip from directly.

This blender has one speed and doesn’t need a control panel. Just attach the blending cup to the blade, place it onto the motor base, push it down to start the motor, and twist it to lock it in place. This makes this NutriBullet  a great choice for people who like simplicity and don’t care about advanced settings. You can also simulate pulse mode by pressing and releasing the cup in short intervals.

Hands-Free Operation

10

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.

We awarded this blender maximum points for this category. It takes little effort on your part to get the job done. 

While several personal blenders demand that we hold the cup in place  throughout the operation in order to engage the motor, the NutriBullet Pro is more fun to use since you can take your hands off it once the cup is locked in place. 

And as mentioned earlier, it never needed extra shaking or stirring to dislodge chunks trapped under the blades; it created an even blend entirely on its own.

7.5

Assembly

9.5

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.

Assembly is the easiest part of using the NutriBullet Pro. Just screw the blade section onto your blending cup, turn it upside-down, and push it down onto the motor base to start blending. Twist clockwise to lock it in if you wish. To remove it, just twist counterclockwise and lift.

8.0

Cleanability

9.0

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.

Cleaning this blender is easy. Simply place the pieces (except for the motor base and extractor blade) on the top rack of the dishwasher or hand wash with soapy water and rinse well. 

Regarding the motor base, you can use a non-abrasive sponge or dish cloth dampened with soapy water. Wipe down exposed surfaces until clean. You may occasionally need a small brush to remove sticky debris from the white actuator tabs.    

The extractor blade, on the other hand, is a little tricker to clean. We found it’s almost impossible to reach the blade’s underside unless you use a straw-cleaning brush.
