Nutri Ninja Blender Replacement Parts, 6 Fins Extractor Blade Assembly for Ninja Blender Auto-iQ BL450 BL451 BL454 BL480 Models Blender Accessories Black

I have the Ninja Professional according to the Ninja Kitchen website this is the replacement blade for BL450 (6 fins). This replacement blade works just like the original. When I compare my old blade to this new blade, they are identical. I order on Thursday and received next day, Friday; I love this one-day delivery. I recommend this blade (6 fins) as the replacement for BL450 Ninja Professional. My smoothies were not the same blending in my Vitamix; I like the convenience of quick and easy cleanup.

My first blade assembly fell apart on its first use. The replacement unit had substantial leaks in the shaft seal. I cannot recommend this product.

Fits our ninja. Blades are very sharp and works great. Check your own ninja to see how many find it has

Got this to replace the origina Ninja blade base that we've been using for years- but the gasket started leaking. Took almost two weeks to arrive, and we found that the additional gaskets this came with are too thick to use in the original, so we still cant use that one. Used this blade base about a week, worked fine with out ninja pro, and then two of the fins broke off the bottom. Useless now, and so frustrated.

ok worked for month stared making loud noise

My ninja blender

Seems like all works well

Does what it says it does.
