Our Verdict

Ninja Blast Max BC251

nutribullet Flex

The Ninja Blast Max BC251 is significantly better than the nutribullet Flex overall, but the Flex does have some advantages. Get the Ninja if you often make single-serve smoothies or crush ice for drinks; it excels in these categories and will produce much smoother drinks and finer ice. Consider the nutribullet if ease of use is your primary concern. It's much quieter and features removable blades that make it easier to clean, which is a rare addition for personal blenders.
