Review on 🔪 Enhance Your Blender's Performance with AxPower 2 PACKS 7 FINS Extractor Blades Replacement Part for Ninja Blender - Compatible with Nutri Ninja Auto iQ Models BL642, NN102, BL682, and More by Joel Mosqueda

So far the quality is similar to the original. Works without leaks and noise. I'm satisfied, but will report if there are problems Update: A little over a month and a week later, after every other day of use, a blade began to leak oil or some kind of brown liquid under the ribs that attach it to the base. The original blade. Of course, the original blade has years stopped before it happened. This one died a week after returning it so I stuck with it. Luckily there were two, but that's not a huge bonus when they broke after a month.
