I was using our Ninja blender over the weekend when I heard a screeching sound coming from the original blade that came with the blender. Given my experience with blenders, I knew enough to know screeching isn't normal behavior, so I paused and checked the blade. It had completely seized up, for reasons still currently unknown, since we regularly maintain our blades and make sure to clean/dry them and not blend hot items. Not sure. Either way, I went online to scope out replacements, and this one looked promising, so I went ahead and ordered one.Initial impressions are great, including speed to ship/deliver. Build quality seems fairly high. If anything, the slightly reoriented blades in the center seem to actually have a better orientation than on the OEM blade (facing the items to be chopped when spinning instead of facing the other direction like on the OEM blade). Fit onto the blender cup and onto the base is 10/10. If you didn't tell me this blade was aftermarket, I wouldn't know it wasn't OEM. I can't speak to longevity yet since we've only had/used this blade for a few days, but we haven't run into any issues yet.That said, I'll update this review if anything changes, but so far, I'm happy with this blade.

Work perfectly, just like the original before we wore it out.

It fits well and works great. It is way too loud and not quite than the original one. Fins are not at an angle to reduce the noise. However, for blending related tasks, it is amazing and does the job efficiently. Given how the blender has its auto mode, I do not need to be in the room. However, your neighbors will likely hate you. It is quite durable as it is up and running for months now. Quite sharp, doesn't leak.

I had the notorious bearing failure in my original blade base. I looked at some different options before coming across this one and I'm glad I did.When it arrived, it right away was sharp and the quality was indistinguishable from the original one I had. It was immediately apparent though that the blades had an improved design.During first use, it did a good job of moving the material around and getting a good blend. Normally I would have to shake the blender to get everything to move but this did it just fine.The only con I had was the blade came loose from the packaging. The nut on the bottom was only hand tight. I took an 8mm wrench to the hex shaft on the blade side and channel locks to hold the nut to tighten it down.

Good substitute

So far, I’m happy with it.

No leaks with great suction. Does what it’s supposed to do.

This seems an aftermarket product and not an OEM; however it fits the NINJA Food processor/Blender combo with circular knob in the front and does the job.
