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

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

Works just the same as the one that come with the ninja been using it for a couple months now at least three times a day no problems

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!!

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.

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.

Was a perfect replacement, perfect fit, but not better than the original. Here we are barely 4 months later, and it developed a crack from the center shaft toward the outer edge. Now it leaks underneath the bottom all over the machine and is unusable. Two stars (1/2 a star/month of usage), and three thumbs down. Won't repurchase it again, it's a waste of money.

just what we needed for our ninja

I bought this in July, 2018 as a replacement for the original, which I had for over 2 years. The blender is probably used 5 - 7 days per week on average. The gasket began leaking after about 3 months, and the thing failed after 6 months- essentially seizing up. I will seek another, better quality replacement elsewhere.
