KOIOS 800W Bullet vs. NutriBullet 900-Watt Pro: The Best Personal Blenders with Their Own Good.

Overall Verdict

If you’re after an all-around blender that can cater to most of your daily needs, from crushing ice cubes into snow to making silky frozen fruit smoothies, the NutriBullet 900-watt Pro is definitely a better choice.

Efficient in its simplicity, your NutriBullet will capture the value and versatility of a standard, full-sized blender—but in a more compact footprint and —pretty well. In our testing, it repeatedly occupied the top spots in every performance in both blending time and blended results. At the time of writing, it is our best-to-buy personal blender and you may hardly find anything better than it, indeed.

The KOIOS Bullet, in comparison, is not as powerful so it is only good for light-duty blending tasks, and you’ll need to cut food into smaller chunks to ensure a thorough blending process. Nonetheless, this blender is quite the apex of the segment with standard features and stable performance.
