[Upgrade] Replacement 6-Fins Female Blender Blade Parts Compatible with Ninja Auto iQ Blenders. [4Inch Female Fins ONLY]

Fits perfectly. Comes with 2 new gaskets. Just have to make sure of the fit, in our case we needed the female blade turning match of motor base.

I'm very happy with this replacement and feel comfortable recommending it to others. It's actually quieter than the original.

What I discovered…..you have to count the fins on the bottom.

The Replacement 6-Fins Female Blender Blade Part was the exact one I needed for my Nutra Ninja. However, the first one I ordered cracked, and I had to send it back for a replacement. It is very hard to find the correct Blade for the Nutra Ninja's because there are so many different types. Very happy to find this one at a great price.

This replacement unit didn't last a year. The blade set started squeaking after a few months of normal use on the Ninja Professional 900 blender. Normally not a good sign. I got a few more uses out of it after the squeaking started, sometimes working ok, but other times not working well at all. It never completely seized up, but it continued squeaking and began to emit a burning smell from time to time. The smell was coming from the blade turret, not the blender motor. One day I pulled it out and tried to spin the blades by hand just to see how it was feeling before I used it, and the blades spun very sluggishly and didn't spin freely at all. I finally ended up tossing it in the trash. I think it's a bad blade design internally. This particular blade set was ordered as a replacement for the first Ninja blade set that was part of the original unit, and which failed in the same manner. The Ninja motor is still working fine. I have come to the conclusion that this blade design sucks, no matter who the manufacturer is. Not with the blades themselves but the internal mechanism where you would find the sealed bearings. Whatever ... time to find another brand.

Perfect replacement good quality, prompt delivery

This saved me from buying an entirely new blender - twice.I’ve purchased this two times now. Both times the new blades worked perfectly, didn’t leak, and lasted quite a long time.CHECK FITMENT! It’s not the sellers fault if you order this and doesn’t fit your unit.

Works great
