In our tests, the Oster BLSTPB-WBL wasn’t particularly impressive, churning out a serving of protein shake, leafy greens extraction, or frozen fruit smoothie with an acceptable texture, but not perfect.  Some of its competitors in this market segment, including the Magic Bullet 11-Piece Set, produced even  more mediocre results. 

Within  the same price range,  the quality of build design between the two single-serve blenders is quite comparable. Both are equally average-built and come with a compact base. However, the Oster BLSTPB-WBL looks more aesthetically appealing due to the sporty design. 

In short, making blended beverages with the Oster BLSTPB-WBL is good for the simple combining of soft ingredients; its 250-watt motor being insufficient for excellent results of heavy-duty blends. But if this is sufficient for your needs and you can make compromises in order to get even blends, this blender would be the  better one to have.

Protein Shake

3.9
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.

The Magic Bullet Protein Shake 1

  • Blending Time: 2 mins 10 seconds
  • Result: Very Coarse

In this test, the two minutes and ten seconds we spent with the Magic Bullet produced an undrinkable result. While all the oatmeal was broken down pretty well, most of the blueberries and almonds came out completely intact. As a result, the drink was too chunky to sip on. It also lacked the fruity flavor that our recipe prides itself on. If you want to use this blender for a protein shake, we recommend just using soft ingredients.

6.0

Frozen Fruit Smoothie

0.0
Oster BLSTPB-WBL 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.

The Magic Bullet Frozen Fruits Smoothie 1

  • Blending Time: 2 minutes
  • Result: Chunky

By our 2-minute cutoff point, the Magic Bullet hadn't fully processed all the ingredients so we considered it to have failed the test and awarded it no points. To be fair, though, the final result was not too bad. While this blender still left behind strawberry chunks, it blended through other ingredients pretty evenly. The smoothie came out smooth; our straw didn't get clogged with hard bits after we removed the two partially blended chunks. It was just quite thin since the blending process was so long that the frozen fruit had time to thaw thus diluting the overall consistency.

0.0

Fibrous Greens

6.0
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: Coarse

If you’re looking for a personal blender that can handle leafy vegetables along with other fiber-filled foods, the Magic Bullet is up to the challenge but will not wow you. 

In this test, its mission was to break down kale, spinach, and celery in 20 seconds. Perhaps, you will get a better result if you blend for longer than we did, but this time frame is adequate for us to evaluate this blender’s efficiency. To check the result, we drained the completed drink through a mesh strainer. As such, we noticed a vast number of leafy chunks remained unblended. The pulp also looked coarse and non-uniform. Still, this outcome is more impressive than those produced by its low-range counterparts.

Crushed Ice Cubes

0.0

  • 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 Magic Bullet Crushed Ice Cubes
The Magic Bullet Crushed Ice Cubes 1
  • Ice Fineness: Chunky
  • Unblended Ice: 83% of 6 oz

Our Magic Bullet couldn’t blend through 6 oz ice cubes thoroughly not only because of its weak motor power but also because its blending cup is too small to handle such an amount of ice. For the most part, the ice got stuck in the blade and prevented it from turning. Even when we undocked the cup and shook it, this still couldn’t help much.

  • 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.

The Magic Bullet is half the size of traditional countertop blenders so it should fit easily into your cabinet. This compact structure also avoids overwhelming your counter space. That being said, the plastic construction means the blender itself is so lightweight that it wobbles while blending.

Build Quality

7.0
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 Magic Bullet Build Quality

All the parts are mostly made of plastic, making the blender look flimsy both inside and outside. Apart from lacking the sturdiness we’re after, the Magic Bullet also has a low resistance to wear and tear. It feels like it could be easily scratched or even broken if accidentally dropped. The blade made of standard stainless steel may well grab your attention but unfortunately, it’s less solid than its competitors at the same price point—the KOIOS, to name but one. So again, the low cost shouldn’t be an excuse for this blender’s shortcomings.

  • 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.

  • Dishwasher Safe:
    Yes

The stainless steel blade has 4 prongs. It comes relatively sharp but looks a bit fragile so we would suggest that you shouldn’t use it for blending hard ingredients without liquid. Otherwise, it may dull or even get permanently damaged.

Motor Base

  • Rated Voltage:

  • 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.

  • Weight:
    1.6 oz (45 g)
  • Cord Length:
    2.2" (5.6 cm)
  • Extra Feature:
    Silicon feet

The motor peaks around 250 watts. It is too weak to be used for ice crushing or dry blending. To make icy drinks, we recommend only using chilled ingredients. Like other personal blenders, it cannot run for longer than 1 minute to avoid damage caused by overheating, though there is an internal thermal breaker that shuts off the unit when it overheats. 

The base has four silicone feet to help keep the whole blender in place while operating. However, we don’t think such add-ons are really helpful; our machine walked around on the counter in every test anyway.

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.

  • Accessories:
    2 lid rings, 3 lids

The set consists of three blending cups. They work interchangeably with the extractor blade and two different types of lids. There are also two removable lip rings included so you may find it easier to sip your drink straight from the cup. 

The drawback is that the lids do not seal tightly to the cup. In the smoothie test, we paused several times to give the cup a shake and eventually ended up with a mess.

Hands-Free Operation

5.8

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.

The Magic Bullet will blend for as long as you press the cup down onto the power base. To stop blending, simply release pressure on the cup, but with the Lock On Mode, your machine can also offer hands-free blending. However, we recommend not letting it out of your sight: Sometimes, solid ingredients like hard nuts and root veggies can stop the blade from turning so you will need to detect this obstruction and intervene as soon as possible. In the smoothie test, we had to shake to unblock the cross blade up to 6 times.

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.

There's a very shallow learning curve to getting accustomed to the assembly process. To blend, you simply line up the tabs on the sealed cup with the tabs on the power base, then press it down until the desired consistency is achieved. 

You can also press down and turn the cup clockwise until the tabs lock under the lip of the power base for hands-free operation. To turn it off, just twist the cup back counter-clockwise and release the cup.

8.0

Cleanability

7.2

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 all the pieces is a snap, especially when the cups and lids are top-rack dishwasher safe, but that didn’t save us much cleanup time. Because of leakage, the motor base got dirty after nearly every blend, though we could easily wipe away the gunk with a damp cloth. Not only that, but the blade’s backsides also gave us a hard time for a thorough hand cleaning so we recommend using a straw-cleaning brush.
