This blade replacement fits my nutribullet perfect. It's difficult to find brand name replacement and this had good reviews so I purchased and I'm very pleased fits on the cup perfectly I use everyday to mix spinach & kale crushed flaxseed powder wheatgrass plant protein powder and wild frozen blueberries! Totally recommended this product.

Was reluctant to purchase online as concerned about the fit. no problems. Great

Good

I was doubtful when I received this. The blades are noticeably more blunt than my original, the area surrounding the blades looks different (fully smooth instead of partially textured). I wanted to test it, so I used it to chop/crush ice for a slushy-style drink. It *was* great.Edit after using it consistently for a couple weeks:This first crushed ice just as well as the original Ninja blade and was even quieter. A couple weeks later, it's not as good. At least, not without pressing it down for longer. Unfortunately not the best when I'm trying not to wake sleeping people. I believe it's due to the fact that the blades aren't as sharp. It's still good, but not great for ice after several uses, oddly enough. I'll wait longer next time, but I also wonder if the extra time it takes to crush ice will further dull the blades faster over time.

Perfect replacement works as advertised. Good quality.

It fits fine and blends food. But seems it’s rusted already and 10x louded. The rust comes out when you turn it on and spin it.

The blade that came with my Ninja was louder and leaked constantly. 5 months in and this replacement is still quieter and holds a seal.

Works well
