This replaces a broken part

happy that this item worked well as a replacement to the OEM part .

I only used it a few times a week to blend a banana & blueberry smoothie, running it for 20 seconds or so at a time. It seemed to work fine for the first week or so, then we noticed our blender sounded a bit different while it was operating. The blade wasn't spinning as freely as it should and I think that caused our blender to work harder causing the noise difference. We could smell the blender motor like it was working hard enough to almost burn out. Within a month of first use, liquid leaked through the blade area into our blender which caused a mess.Basically, the price seems decent, but don't expect it to last beyond a few weeks, especially if you plan on blending more than a few times a week. Disappointed because the blade that came with our blender worked perfectly for well over a year without a single problem. I would not purchase this blade again.

I bought this replacement blade in June for my Ninja Blender 900w BL 450-70. It fits perfectly and works just like the original when it was new.UPDATE: DISAPPOINTED!!!So it turns out that the blades worked well for few uses. After that, I started seeing a lot of rust colored dust coming from the bottom of it each time I used it, messing up the inside of the base unit as well. This just got worst each time, and I just had to throw it out. It also became deafeningly loud while being used. Fortunately for me though I had kept the original blade as they still work somewhat, so that's what I'm using now. Not sure what next to do.

This is our second one, the first lasted around 8 months with daily use before some of the fins broke off.

Was reluctant to order this because of some negative reviews, but I called Shark/Ninja to buy an original but they are no longer available. So, I bought this and I’ve been using for a month with no problems. In contrast to some of the reviews, it does not sound louder to me, does not leak, crushes ice fine, and the splines that drive the blade show no wear or cracks. I’ve been using it for making smoothies several times a week.

Fits Nutri Ninja Auto IQ 1000. Had this replacement less than 2 years and it is cracking and leaks.

A GOOD REPLACEMENT FOR THE ORIGINAL BLADE. I ONLY NEEDED THE GAKET TO FIX THE OLSD LEAKY UNIT BUT THE RUBBER SEAL IS NOT AVAILABLE FOR PURCHASE ANYWHERE.
