Replacement Parts for Nutri Ninja, Blender Blade Assembly and 2 Pack Single Serve 16-Ounce Cup Set for BL770 BL780 BL660 Professional Blender

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.

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.
