Replacement metal Plum blossom gear of Bottom Blade Assembly for Nutri Ninja BL810 30/BL810C/BL810QON 30/BL810QSL 30 /BL820 30/BL830 30/BL830CB 30

we have had this for over 4 months now, & it has worked great for us. its used every day at least twice. it is not showing any signs of rust or discolor. it is not quite as nice as the original but it sure beats buying a new blender!!! I would buy this again.

Works with my ninja but the “blossom” gear on the bottom immediately started to rust after washing and makes a mess whenever wet. Maybe it should not go in the dishwasher? But it does not say that anywhere on it or the sticker that warns of other hazards and the one that I vought it to replace had never rusted though over 8 years of use and washing in the dishwasher (it became worn out and leaky at the point where the blade attaches instead).

Ninja was out of the replacement part, so I bought two of these instead. They both rusted within one or two uses, but because the genuine Ninja parts were not available we continued using them. They have now both started to leak as well. For what it's worth, they were functional while they lasted.

last bottom blade was extremely noisy difference noises laud, thought it was the machine it was just the blade hey not perfect but a lot better

I was going to buy a new ninja, since this one is pretty old. I looked these up on amaz, and for $20 something. It’s like new!!! Win!!

Do f waste your money! I e bought two of these now, a less expensive one, then this. Just searching to replace original that came with blender. Both have been cheap knock offs (regardless of price), and both lasted for all of two uses each. Just do t bother. Zero stars really.

just what we needed for our ninja

This item rusts on the bottom. It's the second one I've purchased and both have rusted.
