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

I’ve swapped this blade like every 6-8 months, not because it’s broken but because water gets in and the bearings get shot. Even the original has this problem. If you smell burning or a loud screech noise when you have it on just buy this. Rinse repeat.

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.

Fits my Ninja blender perfectly. As soon as the blender starts getting louder it’s time to replace the blade. This is the second time I’ve replaced my blade with this brand. Lasts about 3 years with daily use.

Thank goodness I didn't have to buy a new blender! My blade got bent in cabinet and wouldn't turn, I didn't know it until I put it on the blender. It started smoking! When I figured out what was wrong I took a chance and ordered this. It fit fine, just know how many fins you have. It still works, I love my Ninja!

I bought it as a replacement for the original blade that came with my Ninja Auto IQ. Exactly as advertised and it did a great job.

It was perfect! Thank you

I'm not sure which Ninja blender this is supposed to fit, but it doesn't fit mine. The sprocket on the bottom, which drives the blades, is the wrong size. The original sprocket is on the left. The new sprocket is in the right. The new one does not seat into the blender, so the cup cannot go low enough to press against the safety switches.

good product all exactly as described

Hasta ahora funciona muy bien con nuestra ninja CT680

ممتاز

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.

Had this for an about 7 days and it performing without any issues and fits without any problems. Would recommend and purchase again
