Replacement Nutri Ninja 6 Fins Extractor Blade FITS Nutri Ninja Blender Auto iQ BL450-70 BL451-70 BL454-70 BL455-70 BL482-70 Only fit for 18 oz 24 oz.32 oz

This product is a perfect fit and with the two extra seals a perfect buy!!!

It didn’t fit perfectly and I’m pretty sure that it broke my blender. The blender started smoking shortly after starting to use this replacement. Coincidence? I’m not 100% certain.

This is the 2nd replacement blade I have bought for my nutri ninja-and it has lasted a whopping 2 months. Somehow the fins on the blades have been stripped by normal use so I can’t use it anymore. I DO NOT recommend this product.

UPDATE: After using it for a few months, it won't screw down anymore. It keeps popping when I try to tighten it and never seals. And if you think it's sealed, it will leak all over and make a huge mess when you use it!! It's worthless now! Time to keep looking for another replacement. I thought I found a good one!ORIGINAL:Finally found a replacement that isn't crazy expensive and works just as good as the original. I can screw it on easy and take it off easy. Other ones I've purchased I could barely screw on/get off. This one is easy and awesome!

Poor quality and very noisy. Hard when you live in apartment and wake up at 4 am

I tried two back-to-back -- I thought, many reviews, with high marks? -- the props on both had the same stiff, sloppy fit, with a tremendous amount of both play and friction, to the point of molten rubber and smoldering. No.

Perfect replacement. As good as the original

This does not work on the 900 Watt series. I made sure to get one with the 6 fins and right model number and it did not seal well and leaked; I tested it using water.
