Overall Design Scoring

Efficiency aside, the Hamilton Beach’s compact footprint makes it suitable for those who have limited storage space and want to prepare small batches of puree at a time. Still, it is so poorly constructed that we couldn’t consider it a reliable blender. Our Hamilton actually broke right after it finished the final test. 

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.

Overall Usability Scoring

When we talk about ease of blending, we mean the immersion blender in question has practical controls, good cleanability, and a user-friendly design —one that allows you to operate your device with minimum distraction. That said, none of the Hamilton Beach 59765 features meet such criteria. In spite of its simple design, it doesn’t work as comfortably as we’d like. 

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.

Overall Performance Scoring

The Hamilton Beach is designed to be an affordable solution for heavy-duty tasks, but in practice, it ends up a flimsy stick of plastic with low efficiency and inconsistent performance, especially when it comes to processing solid ingredients. If you’re expecting its portability and cheapness to make it fun to use, then you might be surprised to learn its performance was at best dreary in almost all of our tests. For superior alternatives, we recommend considering the Braun MultiQuick-5, Vitamix 5-speed, or cordless Chefman blenders.

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.

Pros & Cons

  • It can be used for pureeing cooked vegetables, fresh fruits, and baby food.
  • Its easy-grip design allows for flexible control 
  • All the accessories are dishwasher safe
  • The motor doesn’t vibrate as violently as others.
  • Extra attachments are included for a wider range of tasks.
  • It is easy to attach, remove, and clean the blending accessories.
  • The silicone buttons are responsive.
  • Its durability is backed up by a 2-year warranty.
  • We don't have to sacrifice efficiency for a bargain.
  • It isn’t powerful enough for many blending tasks
  • The two included attachments are almost useless
  • It isn’t durable due to the poorly-constructed design
  • The blade guard can cause damage to the cookware’s surface.
  • The motor rating is 400 watts rather than its advertised rating of 800 watts.


The KOIOS 4-In-1’s performance could be best described as fine but unremarkable, passing all of its tests with acceptable results. However, compared with the Hamilton Beach 59765, it created a more pleasant yet powerful blending experience without any violent shaking or a loud motor.

Of all the low-range immersion blenders we’ve experienced, it was actually the most efficient one. In certain tests, its results were even smoother than those of higher-priced blenders, such as the Cuisinart. 

Equally important, it is easier to use and clean than the Hamilton Beach 59765. We didn’t have to get used to it, and more often than not, any food residuals were rinsed off easily with soapy water.
