OBERLY vs Koios Pro 850W Bullet Personal Blender

Overall Verdict

The OBERLY and the KOIOS 800W Bullet are contrasting contenders. 

OBERLY capitalizes on its portability, with its compact design and rechargeable feature making it the prime choice for travel enthusiasts. It's the go-to for those seeking spur-of-the-moment blends without the constraints of cords and outlets.

Yet, when performance enters the equation, the KOIOS 800W Bullet asserts dominance. Beyond smoothly creating frozen delicacies, it also excels in extracting nutrients from tougher ingredients like leafy greens, raw nuts, and dried berries—a feat the OBERLY lags behind. Its charm is further augmented by an extensive set of accessories designed specifically for grinding dry.

Ultimately, the decision boils down to individual needs: whether you're captivated by the freedom OBERLY offers or the robust blending capabilities of the KOIOS 800W Bullet.
