- Replacement Blade Assembly Compatible with Nutri Ninja BL660 BL740 BL663 Series, 16oz Cup Only, 6-Male-Fin Base, 3.35" Bottom Diameter, Not for 7-Fin or Auto-iQ Systems

Great!!!!!

Fits my Ninja blender perfectly and works like new.

I've had this ninja replacement cuo blade for about 5 months. Probably used it 20 times max. I have followed all the user rules. I tried to use it today and it LEAKED all down into my blender machine base! It looks as though it has a seem that has opened up. I still have and use the the cup and blade that came with the Ninja Blender I bought 15years ago, it works fine with no flaw. I purchase this one to have an extra. This is super disappointing! I haven't figured out to contact the third party.

You're getting a complete set for the price, and for that, I give it a thumbs up. The lid, the gasket, the plastic base, and the blade is included with the plastic jar. Since it's plastic, it's light weight and safer to handle. It hasn't leaked so far, which was one of my concerns, knowing I couldn't tighten it like my glass jar. In the past when my glass jars have chipped, I have cut my hand accidentally while hand washing them. For me, it's a safety issue, so I switched to plastic. The only downside I can see, the jar is made from a thinner layer of plastic, which gives it a flimsy feeling, so it doesn't inspire you to think it's durable for the long haul, The plastic lid fits awkwardly on the jar (design flaw?) and can be a challenge to remove it (minus one point). I recommend it for because it's a complete set for a good price.

It fit and works great with my Ninja. I love the new cups and the cleaning brush.

Superb, Ninja products are the best.

Peefect replacement fit. You do need to have the specific model

Fits my BL772 30 and fits on my old Nutri cups.

These are perfect. Easy to clean, and work well with my blender set

Worked well with my blender. Too bad the blender started smoking soon after this purchase though.

The product worked well for a short while but the blade is very loud when spinning. It's such a tight fit, it's very difficult to put them on and then take them off. Had to break off the top of the cup to get my smoothie because the blade seems to have bonded to the rim of the cup. Cheap design, don't buy.

I found the parts to be excellent quality and the price was great.

Good quality replacement parts. Fits the blender and works well. Arrived quickly. We are happy with our purchase.
