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.

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

I bought this 7-fin extractor blade assembly for my Ninja Auto iQ blender (model BL480), and it fits perfectly. The blade is sharp, the seal is tight, and it blends smoothies effortlessly — just like the original one that came with my blender. I’ve used it daily for a few weeks with frozen fruit and ice, and it performs great. Highly recommend for anyone needing a reliable replacement part.

Fits. It does a great job blending. I’m not trying to be a wuss, but the blades make such a high pitch noise, that it hurts my ears. I feel bad for my dogs when I use it. I will try a different brand next time.

Perfect replacement for my ninja smoothie blender. Saved me from having to buy a new blender

Leaks at the site where the blade axel exits the spin housing. At least .5 mm of vertical movement of the axel for perfect spilling of your liquid all over your blender motor. Total garbage. Terrible design. O/5 stars.

Is very good

Hasta ahora funciona muy bien con nuestra ninja CT680

Used it today, worked great.

Bought this to replace my previous 6-year old Ninja blender blades which started getting stuck. I’m happy with how well this works, didn’t have any problems, no installation required.

Ótimo, atende as expectativas

Bad quality, after couple of uses it starts to leak brown colored rust or liquid to the food item.
