Oster BLSTPB-WBL vs KOIOS 850W Bullet Side-by-Side Comparison
KOIOS 850W Bullet vs. Oster BLSTPB-WBL comparison. Although neither is perfect, each of these two personal blenders is a good choice on its own.
Specifications
Design
The overall design is thoughtful and well-made for the price. It is developed with extra features that some people might find useful. Not only that, but attention to detail on all parts and surfaces also makes the Oster BLSTPB-WBL a personal blender of hi-tech and refinement.
The KOIOS Bullet comes standard with a compact motor base and stainless steel blades. It features only one speed setting, which is not unusual for this type of machine. Sleek and shiny looking, it has a cute, distinctive personality you won’t find in many rival personal blenders. Unfortunately, its motor base has some poor-quality inner components — we expect better even at this price point.
Usability
Using the Oster BLSTPB-WBL is not much of an issue but requires a bit of a learning curve at first. The most frustrating part is locking the cup with the blade attached in the motor base. Still, once you get the swing of things, it won’t challenge you anymore. Cleaning, on the other hand, will definitely be a problem if you don’t have a bottle brush available.
The KOIOS didn’t receive a higher usability score because it doesn’t allow for hands-free operation. However, it is still among the most user-friendly personal blenders out there on the merits of its straightforward operation, easy assembly, and effortless cleaning.
Performance
As a low-powered portable blender, this Oster was just moderately capable of making protein shakes and frozen fruit smoothies. We wondered if it would somehow be more efficient than its rivals and provide us with fluffy crushed ice or a quick extraction of leafy greens, but it turned out that such tasks were far beyond its strength.
The KOIOS Bullet did relatively well in three out of our four tests. It couldn’t power through ice cubes in the final round, but that didn’t worry us — the same is true for most mid-range blenders. The blended fruity drinks were above average. However, the fibrous greens should be blended longer than our 20-second time limit if you want decent results.

- Powerful motor allows for a wide range of tasks
- Two blending cups are included
- Intuitive to use
- The blades can be removed from the base for thorough cleaning

Conclusion
Both these models are good single-serve blenders considering their affordable price. Although the KOIOS 850W Bullet was slightly more efficient within our testing, we concluded the Oster BLSTPB-WBL is strong enough for any simple blending.
However, these two blenders are not without their drawbacks. Their power ratings were too weak to handle the heavy blending performance well, sometimes requiring a few shakes in order to ensure a thorough blend. Nevertheless, these shortcomings are compromises for the low cost.
There's no clear winner in terms of overall design, as both blenders are quite good-looking with standard plastic parts, but we do prefer the Oster’s appearance for its sporty style, which at first glance is uncluttered and aesthetically pleasing.
