Nutri Ninja Pro Extractor Blades Fits 24oz/32oz/48oz Cups

Great OEM replacement and recommend this to everyone who needs theirs replaced.

This is indeed OEM (original equipment manufacture) replacement. Works like the original -- which I replaced after 2 years of daily protein smoothie making. Two months in, and no leakage so far. Some people complain about the "sour milk" smell that builds up with regular usage. But I simply throw mine in the washer each night, then set to sanitize. You can also use a butter knife to coax the gasket out from the crevice within the lip. Use 1 part bleach or white vinegar to 5 parts water for a good soak before washing with dish soap and warm water. Be sure to dry completely before reinserting. Wallah! Do this about once weekly.

Works and fits the ninja perfectlyUPDATE!!! 2.5 months later and this has to be a fake. It leaks out the bottom as my smoothie is being made! We had replaced our old blade after 2 years of use and it NEVER leaked, it was just dull! We’ve actually gone back to using the old blade and have thrown this one out. It is either defective or fake!! Past deadline window to receive support or return, very disappointed.

I was hesitant to purchase this item because it was not make by the manufacturer. It was quite a bit cheaper so I took a chance and I'm glad I did. It works as well as the original did. I'm hoping it lasts longer.

Very pleased with this. Our original blades started to leak about six months after we started using it. So far this blade is working perfect with no leaks. Looks exactly like the original that came with our Ninja.

I bought this because I damaged the original blade by mistake, it works perfectly it chops and blends as expected. I am so glad I was able to find a replacement without buying a new blender!

the bearing broke down after 6 months of very little usage

This fits larger than 16 ounces. If you have a larger than 16 ounce Ninja, this might fit.
