joystar replacement parts blade for Nutri Ninja Pro Extractor Blades Assembly Works with these models:Ninja Chef High-Speed Blender CT810/CT805/CT805BRN/CT810C/CT800C (1)

Worked amazing the past few years.

I didn't read the description. I ordered this set not knowing I was also ordering the blade. I didn't need the blade. What I needed was the cover for the blade. That didn't come in the box, for that Im very disappointed. Though, price was good for what your getting.Update: it’s going back because it does not fit my Ninja model CT672A Smart Screen Kitchen System

I did not like the fact that is very hard to place and remove from blender.

There is something wrong with the way the threaded portion of this blade assembly was made. It barely engages the threads on the cup (and we've tried several different cups). The most frustrating part is when it "pops" loose and everything that was in the cup dumps all over the blender and counter. I'm tired of fighting it and will be returning this for a refund.

Worked fine for 2 months. The fin side has some metal that rusts.. It broke after 2 months and left plastic in the smoothie... I'm trying a different brand next time.

Cups are great, but the blade bearings leak and are very noisy

It has a hairline crack in it. When I put it in the blender and put the vacuum, air comes through with bubbles and never gets a vacuum seal. Also leaks through where the blades are mounted through the base. I used it 2 times.

After two weeks around the gasket. Not good!

Lame pro extractor supposé fonctionner mais n’a pas été concluant. J’ai été remboursé sans problème donc pour cette raison les 5 établies ☺️

Merveilleux pour préparer les smoothies merci
