La Reveuse vs Koios Pro 850W Bullet Personal Blender Side-by-Side Comparison
La Reveuse vs KOIOS Pro 850W Bullet. While La Reveuse has many strengths, there are limitations that prevent it from being a better choice over the latter.

Specifications
Design
The La Reveuse is built for the price with a basic set of features. Its simplicity is a big draw, but the lack of upscale feel ultimately holds it back. To be blunt, the plastic housing feels cheap and does not give a sense of durability. We had hoped for a blender that was not only efficient but also visually appealing, but this one falls short in drawing attention to itself. There is a lot of room for improvement should this blender want to become competitive with its peers. Sharing the same kind of styling, the Oster or the Black+Decker looks more eye-catching and beautifully sportier.
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
The design is very intuitive so finding how this blender works didn’t take us much time at all. There is only one speed option, but we found it was rather easy to get pulse mode by pressing and releasing the cup in short intervals. Hand washing the cup and the blade’s backsides was challenging particularly due to their styling, but if you have a cleaning brush available, you’ll get all things spackling again in no time.
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
In our test, the 300-watt motor of this blender was just sufficient for smooth blends of frozen fruit smoothies and fibrous mixtures. It didn’t mix protein shake as evenly as the counterparts. It also fell short in crushing ice cubes, though this appears to be the case with most mid-powered personal blenders. If you want more capabilities than what the La Reveuse offers, there are the Ninja Fit, NutriBullet, and the Ninja BN401 Nutri.
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.

Conclusion
The La Reveuse, equipped with a 300-watt motor, exhibited commendable aptitude in blending fresh plant-based ingredients. It managed to yield satisfactory results with fibrous greens and frozen fruits. Yet, it faced hurdles with more demanding tasks, such as crushing ice cubes and blending oatmeal, raw nuts, and dried fruits.
The La Reveuse, with its 300-watt motor, displayed impressive proficiency in blending fresh plant-based foods. Nevertheless, it slightly managed to yield satisfactory results with fibrous greens and frozen fruits. It even faced hurdles with more demanding tasks, such as crushing ice cubes and blending oatmeal, raw nuts, and dried fruits.
Conversely, the KOIOS Bullet, sporting a robust 850-watt motor, consistently delivered impressive blending capabilities. It adeptly handled ingredients that the La Reveuse was incapable of, with the exception of ice. Its expertise in preparing frozen fruit smoothies was also noteworthy. Plus, while its performance with leafy greens wasn't exemplary, a slightly extended blending duration promises enhanced outcomes.
In sum, while both blenders have their strengths, the KOIOS Bullet stands out as the more versatile and efficient choice, especially when weighing in its generous set of accessories and the stronger motor.
