The two are basic, mid-range immersion blenders. In our efficiency testing, however, the KOIOS 4-in-1 outperformed the other. Compared with the Chefman 6-in-1, it blended frozen fruits faster and produced more silky pureé. It also ground nuts more evenly, churning out a serving of milk that was apparently richer in almond flavor.

Design-wise, they are pretty evenly matched, with reliable build quality for daily use. Still, we mostly agree the KOIOS 4-in-1 looks more catchy. Its design also allows the motor to run smoothly and is more comfortable to use on tough blends. In conclusion, if you have to choose between these models, we’d like to recommend the KOIOS 4-in-1 over the Chefman 6-in-1.

Pros & Cons

  • 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 can blend frozen fruits, chop vegetables, emulsify sauces, and beat eggs.
  • The motor runs quietly.
  • Its accessory package includes many helpful pieces.
  • The ergonomically-designed handle provides a comfortable grip.
  • 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 metal blending shaft and whisk damaged our cookware’s surface.
