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

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!

Fits perfect, just like the original.

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.

Update 5/28/2022: The replacement worked fine but the blade axle felt a little loose, clicking up and down slightly. Rusty water started running out after a couple of months. In addition to that, the axle became worse and didn't connect properly to the blender, ruining the plastic part of the blender that locked into it. Now the blade is unsanitary, the blender is ruined, the return window is closed, and there is no contact for the seller. AVOID AT ALL COSTS!!! The unit fit poorly on our blender though it was listed as a match. We had to hold the cup by hand so it wouldn't become loose while blending a smoothie. After a couple of days the metal axel right under the blades burned up, making the part useless. Grateful for Amazon returns!

IT IS GOOD

Perfect fit for my replacement and great value for

Easy item to buy for making the device to work again!

My ninje blender was not blending like it should. This blade replacement fixed the problem

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

It’s a perfect fit for our Ninja machine and performs really well.

No tengo mucho que decir, excepto que esta base de repuesto le quedo perfecta al modelo de mi Ninja (BL780CO 30). No se que tan durable sea, pero ya llevo un mes con el producto, y no han sufrido ningun desgaste. Definitivamente lo volveria a comprar.

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

y el costo, ni se diga, compré unas en la tienda de la marca en $650 y compré estás y salieron mejor.
