Ninja Nutri Pro Compact (BN401) vs. KOIOS Pro 850W Bullet Personal Blender

Overall Verdict

The Ninja BN401 stands out as a top performer in the personal blender market, with advanced features and heavy-duty performance. Sporting a mighty 1000-watt motor and an upscale blade design, it proved to be excellent in all areas. It is also surprisingly fast, typically taking just one minute to create a perfect smoothie with frozen ingredients, while other personal blenders might need double the time. 

On the other hand, the KOIOS Bullet is a budget-friendly option that offers adequate versatility and extra accessories. Although it may not have the same heavy-duty power as the Ninja BN401, it still delivers smooth results for most recipes, including frozen fruit smoothies and protein shakes. The only area where it falls short is crushing ice cubes. 

Ultimately, your specific needs and budget will determine which of these blenders is the right choice for you.
