1-pack Extractor Blade Assembly 7 Fins Ninja Blender Blade Ninja Blender Replacement Parts Compatible with Ninja Blenders Auto iQ BL480 BL482 BL642 BL682 NN102

I love my Ninja Blender so much. I make a protein shake every day, one with plenty of ice cubes and sometimes fruits and vegetables. The higher watt motor of the Ninja makes it all work perfectly. But these dang blender blade assemblies don't hold up. I imagine the problem is the amount of torque exerted by the 1500 watt motor. The black plastic that holds the blade in place always develops cracks, and then my protein shake starts sneaking through those cracks as it is being blended. Also, the blade element gets a little bit loose, which allows some other leaking. I've tried tightening it (it's tricky because you have to do the opposite of what feels right). Most of these assemblies last me less than 6 months, including the one that came with the blender and was (I assume) made by Ninja. Still, buying a new one of these every 6 months or so is cheaper than buying a new blender. It comes with a gasket that slips into the depth of the threaded part and should help prevent leaking - it does, but only in the part it is protecting. That gasket can't do anything about leaking through cracks in the plastic. I believe that, although the blades are quite sharp, the real work of blending happens through the creation of cavitation pockets . . . that takes a powerful motor.

Item: Extractor Blade Assembly 7 Fins Ninja Blender... Seller: PODCAY Tl;Dr: Looks like OEM, but poor quality. No support from seller. Per Amazon, seller is from China and is uncommunicative. --- While it looks remarkably similar to OEM and performs similarly, it does not last long. Original one lasted about a decade while this after market broke down just after two months. Its ball bearings had failed - even if manufacture uses better bearings, I would appreciate a redesign that allows consumer to replace ball bearing themselves with ones sold on Amazon. Will reach out to seller for warranty/replacement and update review as needed. --- update --- So Amazon support is hit and miss. Some people helpful - some not. First Amazon agent, Amarpali, said they would send a message out to seller and that the response will be within 72 hours. I had Amazon agent Burada confirm this. Days later, no response so I reached out to Amazon and was connected to agent Mohammad Altaf. He didn't seem to understand that I wanted to reach out to manufacture for warranty support and quoted return policies and brought up return window. He then suggested I repurchase the item. I retyped my request (guess I should have just told him to scroll up on the chat conversation and re-read) that I wasn't requesting a return, but was requesting communication with seller for after-sales service. Got a message shortly after that Mohammed was having "techincal difficulties"... Re-connected with another Amazon agent, Nikhil, and he informed me that this seller, Podcay, was from China and is unresponsive (!), and proceeded to resolve my issue.

Perfect fit, works just like brand name

Love this. Had to replace our Ninja blender blade because we used it every morning for smoothies. I love the design and quality of this blade. It works really well with our Ninja blender.

Works great. You may need to hold down while blending

Great iem. should have got one sooner since my original with the blender had started leaking some during use. this is a greatly replacement and works just like the original

This is what we ordered and it works great

[Update below] I hate bargain knockoffs. I find myself always buying twice. The original blade was always out of stock on Ninja’s website. And I needed a new one asap. I decided to give it a shot. Shockingly, after a few uses, I couldn’t tell the original apart from this one. The quality and build, the sharpness of the blades, etc. all seemed identical. I suspect they’re from the same manufacturer. And probably why Ninja doesn’t care to stock it since they didn’t lock up exclusive rights on the design. That being said, I ordered a second on after all, not to replace this one, but out of sheer convenient affordability; we blend a lot at home and a second set solves the “is the ninja blade in the dishwasher?” dilemma when you just need it. **Update** Both began to leak rusty brown grease from the bearings. (pictured on the paper towel after wiping it off the plastic back) They then got louder and louder. And ultimately began to smoke during use. And finally completely seized. I replaced them with another vendor that claims others were using carbon steel, rust prone, cheap bearings (makes sense). And that their version uses stainless steel bearings. It’s been night and day in terms of sound and performance. It was sold in a two pack for nearly the same price. Not sure if I can link to them here. But I would avoid this one here like the plaque. It’s garbage and I should’ve waited before ordering a second so soon.
