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.

Pros & Cons

  • The motor doesn’t vibrate as violently as others.
  • Extra attachments are included for a wider range of tasks.

  • 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.

  • 4-pronged heavy-duty blade promotes speedy blends and consistent results
