The Ninja QB3001SS Fit is a formidable foe of not only the Oster BLSTPB-WBL, but also of everything else regardless of the market segment. It easily won against its competitors in every test, churning out  quick results that were almost velvety. Its overall design is also more impressive in numerous ways. 

Despite not being as efficient nor as versatile as its rival, the Oster BLSTPB-WBL does have its own worth though. While it wasn’t successful in the crushing ice test, and wasn’t nearly as good at blending fibrous greens, its motor produced sufficient power for our frozen fruit smoothie and protein shake. 

In conclusion, the Ninja QB3001SS Fit is a perfect option for every need, but if you cannot afford the extra $20, the Oster BLSTPB-WBL may still be an acceptable alternative for simple blends.

Protein Shake

  • 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.

  • Blending Time: 50 seconds
  • Result: Silky Smooth

No matter what ingredients you have on hand for your protein shakes, the Ninja QB3001SS Fit will quickly turn them into a chunk-free mix. Its impeccable performance in this test is evidence of that. Consisting of the toughest-to-blend ingredients, our recipe presents a high level of difficulty, but it still didn’t give this blender any trouble.

Our Ninja took only 50 seconds to churn out the desired result. The oatmeal was completely broken down while almonds and berries were blended to their finest state. After straining the drink through a strainer, we found a smattering of partially blended chunks, but we don’t think it's enough to turn off many folks. Given such a result, this machine is a worthy competitor to the NutriBullet — our favorite personal blender at the time of writing.

Frozen Fruit Smoothie

  • 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: 1 minute
  • Result: Silky Smooth
  • Suction:

When it comes to preparing smoothies, this blender’s efficiency is something that we’ve all dreamed about, but never thought possible on a budget. In our test, it allowed for a quick preparation of frozen foods with very little effort thanks to its heavy-duty motor and sturdy blades. The compromise was that we had to pause now and then to shake chunks free from the blades.

The smoothie was ready to drink within 1 minute of blending, which was far faster than average. In fact, it was fully twice as fast as some other models like the Magic Bullet, the Hamilton Beach, and the Oster. You may think it doesn’t matter much to wait a bit longer, but actually, the difference in blending time between blenders did create a substantial discrepancy in the drink’s texture and temperature.

As a general rule of thumb, frozen foods thaw quickly at room temperature, especially when you start grinding them up. The faster your blender does its job, the thicker and less diluted your smoothie will be. 

Simply put, not only did the Ninja Fit blend smoothly, but its rapid operation also provided us with the thick, ice-cream-like consistency that we prefer in frozen fruit smoothies. If you’re craving icy-cold drinks on hot days, this blender definitely has the chops for it.

Fibrous Greens

9.5
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: Very fine

The Ninja Fit is quite capable of incorporating leafy vegetables and other fiber-filled foods into your drink. Of all the blenders we tested, this was one of the few that could break down almost all of kale, spinach, and celery in only 20 seconds. The greens were blended finely and had consistent-sized grounds. Not only that, but it left us with only a little pulp that was too big to pass through a strainer — better results than even the Nutri Ninja.

Crushed Ice Cubes

  • 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.

Ninja QB3001SS Fit Crushed Ice Cubes 1

  • Ice Fineness: Very Fine
  • Unblended Ice: 20% of 6 oz

In this task, this blender struggled quite a bit, and couldn’t quite power through all the ice cubes. A small amount of ice remained solid — accounting for 20% of the total — when it was all said and done. And again, we had to stop and shake the blending jar to promote the contact between the ice and blades.

Of all the blenders with small blending cups, however, the Ninja Fit was the only one that actually could perform that well. It even crushed ice as fluffily as its larger counterpart, the NutriBullet. With the Ninja Fit, you may no longer have to deal with whole ice cubes in your drink.

  • 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.

  • Shaft Length:

This blender isn’t as solid as the NutriBullet or the Nutri Ninja, but we appreciate its lighter weight and more compact dimensions. It is roughly the same size as a champagne bottle, so it should fit well into your cabinet. It also won’t occupy too much counter space and you can easily carry it around when you’re on the move.

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.

The Ninja Fit Build Quality

Our Ninja Fit looks fancier than we’d expect for the price. The part quality resembles that of much more expensive units. The main body’s exterior is eye-pleasing with a glossy finish capable of holding up against dings or scratches. The interior is mostly made of plastic, but it looks robust, reflecting the blender’s high-tech design. Much the same can be said for the blending cup and extractor blade, too. These parts aren’t new ideas, but they should be the benchmark for durability and refinement in this price range.

  • 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.

  • Material:
    Stainless Steel
  • Type:
    Sharp Blade
  • Guard Material:
  • Blade Count:
    4
  • Removable:
    No
  • Dishwasher Safe:
    Yes

The blade is constructed of hardened stainless steel. It features four prongs so you will get faster blending times and finer results compared than those that have only two. 

The base and blade assembly screws tightly onto the blending cup to prevent leaks while in use. It is designed for processing liquids, including juice, frozen mixtures, sauces, and hummus. It cannot be used to blend hot liquids or for grinding operations.

  • Cord Length:

  • 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.

  • Extra Feature:
    Rubber grips on the bottom, cooling fan.

The Ninja Fit is powered by a 700-watt motor which is more than enough to blend most simple ingredients. That motor is even strong enough to turn your blender into a standalone ice crusher, though we don’t recommend doing so too often since it might limit the blender’s lifespan. 

The elegant yet sturdy exterior is a key selling point over its rivals, but the carefully constructed interior is what truly grabs our attention. In particular, despite being made of ABS plastic, the black actuator tabs are unlikely to break even when you press the cup down into them vigorously. The rubber and plastic liners inside the power base feel pretty durable too. 

There are also rubber grips on the bottom that keep things steady while in use and a cooling fan in the back to limit overheating. Still, though, it’s best not to run it for more than a minute at a stretch.

    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

7.8

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.

This blender doesn’t allow for hands-free operation; you’ll need to hold the cup in place throughout the operation to activate the motor, but this is true with most personal blenders. On the upside, it doesn’t demand too much extra shaking or stirring to dislodge chunks trapped on or around the blades. For the most part, each batch only needs a little shake to achieve a smooth consistency.

7.5

Assembly

10

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.

This blender is a cinch to set up. To blend, you’ll need to seal the blade tightly to the cup, then turn the cup upside down and place it on the motor base by aligning its tabs with the motor’s slots. Once your cup is correctly positioned, push it all the way down so it can begin blending. Removing the cup is even easier, simply lift it up from the motor base. You won’t need much practice to operate the machine smoothly — we figured it all out before even opening the user manual.

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.

All the parts are dishwasher safe except for the motor base, but note that they must be separated from each other before being placed in the dishwasher.

To clean them manually, simply pour warm water into the cup, add a bit of soap, and run the blender for 30 to 60 seconds. After dumping out the cleaning solution and rinsing the pitcher thoroughly, your blender will be ready for a new batch of smoothies. 

If you  don’t want to do it that way, we recommend using a dishwashing utensil dampened with soapy water to scrub out any stains. Getting under the blades can be tricky; be careful not to slice your fingers!
