## Questions & Answers

**Q: Will this fit  a 24 oz cup for ninja chef  model ct 810?**
A: Not sure, love. I use it on a auto-iq nutri ninja. If you go to ninja website, I think it lists the replacement parts. It looks the same but I can't be sure. It goes by the number of spokes that fit down into blender.

**Q: Does this replace blade come with the black plastic lid that screws on or is it just the blade?  every picture shows the blade connected to the lid**
A: You mean the black plastic that has 7 fins as shows in the picture, right? 
yes, it come with the 7 fins black plastic that can be screwed on the blender cup.

**Q: Is there a way i can get the rubber ring alone?**
A: yes.  I would do a search for Silicone Rubber Gaskets Seal Ring for Nutri Ninja Auto iQ.  Make sure that you get the silicone one.   ie:  https://www.amazon.com/SunnyMemory-Silicone-Replacement-Extractor-BL456-30/dp/B09LS3CVDW

**Q: Do you carry this same ype of blade for your BL494 Model?**
A: Yes

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great value works perfect
*by I***Y on 13 August 2025*

Absolutely fantastic, It’s perfect, my old one was leaking brown for a year .The price of this was brilliant I’m happy I didn’t have to get a new blender altogether,Just don’t screw it too tight to your blender cup I would say and don’t put it in the dishwasher ever!!!

### ⭐ Cheap Alternative
*by M***N on 7 September 2025*

Item only lasted 4 months, absolutely rubbish. Go and buy the original part from Ninja.

### ⭐⭐⭐⭐⭐ Good fit
*by A***R on 7 August 2025*
