The first time this part went bad on my Nutriblender, I bought another one. Then I found out about these and have probably replaced them more than 1/2 dozen times - no new blender! It seems like whether it is the orignal part or replacement part, the bearings wear. At the point you see (and this sounds disgusting) brown slime in the tray these lock into, just replace this part - the motor has consistently been fine and these are perfect replacements! Read more
Perfect! I bought the blender from Amazon. Amazon did a quick search on my purchasing history to identify the correct replacement part. I was so pleased with the service and product. Read more
These impeller cogs are made of rubber that is too soft to handle the torque of the motor. The cog pictured on the left is the MEET JUICE replacement impeller cog that stripped after only 9 days and 9 smoothies! The cog on the right is the original Ninja impeller which is over 5 years old! You can see the difference in the cog tooth heights (leftmost picture), how badly the soft rubber cog teeth of the MEET JUICE part shredded away (middle picture), and how well the original Ninja impeller has kept it's shape and height, after 5 years and probably more than 2,500 smoothies. I only replaced the original because the seals finally gave out and it was leaking. I grind hard materials in my smoothies. I use milk or almond milk, yogurt, cottage cheese, fruit of some type, raw egg, whey or collagen powder, avocado, and water. LOOK AT THE PICTURES, DON'T WASTE YOUR MONEY ON THESE PARTS!! Read more
These blades fit perfectly and are working very well. Read more
Good replacement brades could be a more sharp but dose the job Read more
Direct fit. My blade assembly was loose. I could visibly see and physically feel some plat when I wiggled the blade. I could see smoke when I removed the blender bottle from the blender. I could also see remnants of the substance i was blending had leaked through the loose blade. On top of all that it was noisy. If whisper quiet was a thing when it comes to a Ninja I would say it was that quiet when I blended my smoothie, but it was never that quiet out of the box, however; this blade made me feel like I had just changed the oil and filter in the truck and bought brand new tires. It runs smooth. Read more
When I first got it, back in June 2025, it appeared to work well. However, I soon noticed that the plastic base and the metal blades soon started getting loose and liquid would leak from from the under side. Though you can tighten it, provided you use some sort of towel to hold the blade, it wasn't as easy and would still leak. The other other base had a rubber seal that was way too thick and was useless, I was unable to remove the rubber seal no matter what I tried. Read more
Perfect replacement for a seven fin ninja. I think this is the second purchase. I make a fruit smoothie five days a week. I think these last about 8 months each. They seal perfectly and are quiet in their operation. I never put them in the dishwasher, just rinse and let them dry. My standard smoothie recipe 1/3 frozen mango. 1/3 frozen strawberry, 1/3 frozen blueberries, a few walnuts or almonds, a tablespoon of baking cocoa, enough milk to get it to a drinkable consistency. I combine the ingredients, except the milk I add that in the morning, the night before and let it all defrost in the fridge overnight, mix it up in the am and this is my breakfast on the way to work.
