6 Fins Blade Fit for Ninja Blender BL660 1100w, Fit for Ninja 16 oz Cup

Fits perfectly!

Glad to find this replacement part!

Smoothies are great again

This does not work with my Ninja BL660. Every time I use it to make a smoothie, when I take it off the blender, I have to end up cleaning the inside of the blender due to it leaking. I have tried to make this as tight as possible but it still leaks. The rubber gasket is inside but it still leaks. There's nothing more frustrating that having to constantly clean up after using this product. I am going to try a different brand but I am definitely not happy with this. UPDATE: This practically caught fire 🔥 internally the last time I used it. Pulled it off and the inside was billowing nasty smoke. It's actually fused tight. My blender still works with my larger blender but this thing is definitely fried.

Great replacement piece

I was hesitant to order this Ninja replacement blade, worried it might not fit properly or be substandard—but I’m so glad I took the chance. It arrived quickly, and when I compared it to my original blade (see photos), I noticed it was slightly heavier with a bit thicker blades, but overall it fit perfectly and matched the form of my old blade. I washed it, rinsed it, and used it right away to make my matcha tea with boiling water, milk, MCT oil, fiber, and protein powder—and it worked flawlessly. My old blade had been leaking and making alarming noises, so this new one put my mind at ease. The only hiccup was a faint plastic taste in my first batch. I gave the blade a long soak in very hot soapy water and washed it thoroughly, and the next batch was perfect. My advice: be sure to wash the new blade well before first use to remove any residual plastic taste. Overall, a solid, reliable replacement that is extending the life of my Ninja blender!

This 6‑fin blade assembly is a solid, well‑made replacement for compatible Ninja models like BL660, BL770, and BL740. The product works perfectly on my NINJA BL780 I just can suggest to to confirm your cup size (16 oz only) and blade diameter before ordering — it’s not compatible with 24 oz or 32 oz cups.

Excelente producto, cumple muy bien su función

Fits perfect and has worked well since replacing the old part.

We had a burning smell, thought it might be the motor but thankfully a new blade was all it took. Quick delivery.

Overall: Amazing! Works perfectly, no leaking. I read the product description and insured that it was compatible with my Ninja blender. Pro: Great price when I bought it, has never leaked in the 3 yrs+ of owning. Con: A bit tricky to clean.

Made a smoothie one day and ended up dropping the spinner on the floor and a piece broke so I had to use the large container all the time. Got an idea to look on Amazon and found a replacement and it’s fits great and doesn’t leak either.
