Let me just say, I didn’t think my trusty Nutri Ninja, which has been blending up smoothies and questionable late-night concoctions for almost 10 years, would live to see another day. But this 7-Fins Extractor Blade Assembly swooped in like a superhero, saving me from shelling out for a whole new blender.The blade is sharp, fits perfectly, and works like a charm—my 10-year-old blender feels practically brand new! The rubber gasket is snug and leak-proof, and it handles frozen fruit and ice like a champ. No more weird squeaks or the faint odd smell that I was trying to ignore.However, let’s not pretend it’s all sunshine and rainbows. The price had me raising an eyebrow (hello, it’s just a replacement part), but when you factor in how much a new blender costs, it’s still a win. Also, with the spare gasket, you can't go wrong.Overall, this replacement part has breathed new life into my blender and saved me from adding another appliance to the landfill. If your blender is old but gold, this replacement piece is totally worth it. Blend on!

Bought 3 of these. They make a terrible amount of noise. I thought the noise was temporary but it has been months now suffering them, nothing has changed and I can no longer return them. Waste of money. I hate them so much I'm trying other sellers.

As expected

Perfect fit!

I got about 9 months of daily use out of this. Then the plastic base developed large cracks. By comparison, 2+ OEM units lasted over a year each, but were much more expensive. Another low-cost replacement lasted about a year. These other units all failed in the bearing assembly.

My old blade was starting to not spin on its own. Did find a youtube video about using olive oil to relubricate the blade which helped a lot. Also, there are some notes about Ninja having a great warranty and being good about replacing parts. Still, I bought this blade. The price is reasonable and if it works well my Ninja can be used for a few more years. The new blade is very similar to the original. The differences aren't worth mentioning. The biggest problem I had was the bolt through the bottom wasn't connected to the blade yet. Took me like 5 minutes to realize it is a left-handed bolt. That means you tighten in reverse of most bolts we know. After that I've been very happy with it. Also, the blade comes with a gasket installed. The spare gasket isn't needed yet but might be nice down the road. Would recommend.

I bought this extractor blade for my Ninja Foodie Power Blender Ultimate system. It worked fine for a little while but then the machine got so loud that I could not use it any longer. Also, a ring of brown fluid would form on the under side of the extractor. At first I thought it was the base that was the problem.I called Ninja, and while I was no longer under warranty, they kindly sold me a new base at half price.There was no change at all in the loudness when using it, and the brown liquid still formed under the base. At that point I ordered a new extractor blade directly from Ninja. It looks the same, but no unbearably loud noise when using the appliance, and no brown liquid ring underneath.It must be the knock-off brand blades are not properly balanced or something, I don't know. But no more "compatible" extractor blades for me.

I’m so frustrated with how quickly these lock up or the bearings go out. I love my Ninja blender. I make smoothies every day. It seems that I have to buy a new blade assembly every 5-6 months.
