Overall Design Scoring

Nothing is particularly unique in the KOIOS 4-in-1’s design, but common features like the stainless steel blades and control buttons are built well enough to make the blender itself stand out.

During our testing, we noticed that balde friction from a prolonged operation would cause the motor to overload. That’s why it’s best to avoid using this blender continuously for more than four minutes. The Vitamixt cannot protect itself from overheating, though it is designed to flash a pattern of LEDs to indicate when your motor is over temperature.

Overall Usability Scoring

Despite utilizing the same key design features as other low-range blenders such as the Muller Ultra-Stick, the KOIOS 4-in-1 manages to provide a better blending experience.

Initially, we assumed that the Vitamix’s weight would cause it to be less user-friendly. However, after a course of testing, we realized that our assumption was entirely wrong.

Overall Performance Scoring

The KOIOS 4-in-1 wasn’t designed for powerful performance, but it passed all of our tests without much difficulty. As you might assume, a low-range hand blender won’t churn out velvety results, but all the blends were definitely better than we expected.

Among the range of models we put to the test, none matched the efficiency or quality of the Vitamix. Powered by an impressive 625 watts, it stands as one of the most powerful blenders on the market. It works swiftly, taking much of the physical strain out of the process. Once it's in action, the blender efficiently pulls ingredients towards the blades, ensuring a consistent blend. However, for achieving an optimally uniform texture, a little manual intervention in the form of moving the blending wand around in the ingredients could be necessary.

Plenty of brands claim their immersion blender can deliver a strong performance, but the Vitamix is among the few that really make us feel like we can blend just about everything in our kitchen.

Although it’s expensive, it warrants the higher cost with its velvety blended results and superior durability. Compared with the KOIOS, it weighs a little bit more, and its blending shaft is a little longer. That stated, it’s still portable and well-balanced enough to help us blend without hand fatigue. 

If you go with this high-quality blender, it certainly won't take long to prepare a batch of smooth whole-food combinations.
