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.
The NutriBullet Pro is not revolutionary, but we love its simplicity and sturdiness. It delivers decent quality at an affordable price so you can blend with peace of mind for years. It also comes with several handy features that may interest you.
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.
The NutriBullet Pro perfectly fits our definition of a blender with good usability. Its straightforward working mechanism is a breeze to learn and use. It is also among the simplest to clean and assemble. So far, we don’t have any complaints about this little workhorse.
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.
The NutriBullet Pro sports a 900-watt motor. It is more powerful than most personal blenders, passing all of our tests with outstanding results. Given its impressive testing performance, we’re confident that hardly anything will offer this blender a challenge. It will be your quick and convenient way to transform any whole foods into nutrient-dense treats.

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.
