KOIOS 850W Bullet vs. Ninja QB3001SS Fit: The Face-Off of Two Valuable Personal Blenders

Overall Verdict

These two blenders share the same market, but the Ninja QB3001SS Fit seems to look sturdier, and in our tests, its results were much better than those produced by the KOIOS 850W Bullet.

Whether we tested it for processing frozen fruits, or oatmeals and raw nuts, it stood out from its rival with a faster blending performance and smoother outcomes. Its ice-crushing capability, though, is something that KOIOS’s owners will have to go without. 

However, that does not imply that the KOIOS 850W Bullet is inferior, especially since this blender produced acceptably even blends, except for the fibrous greens and ice crushing tests. We don’t recommend it over the Ninja QB3001SS Fit simply because it’s not as good value for the money.
