2 PACKS 7 FINS Extractor Blades Replacement Part Bottom Blade for Ninja Blender for Nutri Ninja Auto iQ BL642 NN102 BL682 BL2013 and More

I have used it a handful of times now and it has worked perfectly fine. Full disclosure- I’m only blending protein shakes so it not like I’m requiring it to to that much, but to date I’ve had no issues.It fits my cups, it fits my base (be sure you count how many fins your Ninja has...it’s not that hard!), and it hasn’t leaked. The gasket wasn’t fully down in place when it arrived - but they tell you that right up front - so just follow instructions and inspect it before using.Our original Ninja blade began to smell really awful - at first a good cleaning seemed to help, but shortly thereafter it just smelled so awful that it started impacting the smell of whole pantry where we stored it between uses. Even ran it through the dishwasher, opened the door afterwards and the whole d/w smelled awful! For context, our Ninja is maybe 7-8 yrs old.I’ll update my review of our new blade if anything changes, but so far, for the price and convenience - and no smell - I’m extremely satisfied with it.

Both blades stuck and no longer spun freely after less than one year of use and being minimally used. Without realizing the problem, I tried using one on the ninja blender. The increased strain caused the motor to overheat, smoke, and break. This product defect led directly to the failure of the entire unit. I am extremely disappointed with this purchase since now I have to replace the whole ninja blender.

The AxPower 2 Packs 7‑Fins Replacement Blade is a smart and economical choice for keeping your Ninja Auto‑IQ blender running smoothly. With two blades included, solid build quality, and broad compatibility, it’s an excellent backup or replacement option.

Works as expected. It does work on the ninja blender. I would purchase again but I gave it a 4 out of 5 because it isn’t as good as the blades that come with the ninja blender.

All I can say is DO NOT THROW AWAY your Ninja when you start to see leakage (mostly a brownish color once it goes through the bearing) on the base, or it starts to sound labored or louder. I have found that the replacement blade part of the Ninja is almost disposable - we probably have replaced it every 3-6 months. I have bought these replacement blades in a two-pack at least 3-4 times (the main - expensive - Ninja base is fine). My original Ninja purchase was one with additional options - including the larger blender, the drink cups, etc, so didn't want to just pitch it. It is crazy to think that the blade part goes bad so frequently, but the bearing does take a beating and buying these replacements is the best economical (and even eco) option. Just wish the blade component lasted longer - but can't fault the replacement blades for that - so "5 stars" on functionality!

Good quality

Ordered December 4,2021 and these are already leaking around the blades and are leaking into the motor of the unit which will ultimately burn up the motor

I would give these a 0 if I could. I was so disappointed. I have bought so many replacements over the years. Love the Ninja but the replacements are a crap shoot. Some last for years and this set lasted a month or two. Once they become very loud they are ready to die so be prepared. The blades lock up, bearings go out, and smells like it's burning up. Throw them out before they throw grease into your smoothie.
