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 just got and used these replacement blades and so far so good. It fit my 7 fins Ninja Professional blender and it works same as the original one and the price is good; two blades with rubber gaskets already installed plus two extra rubber gaskets and a cleaning brush. Now remains to be seen how long it lasts.Make sure you match serial number (or within serial number SERIES) of your blender found at the bottom of the motor for example mine is BL455 30 and I purchased BL457 30.

This blades are very good for my Blender.

I was excited to receive this product and thought it was going to be great. Two replacement blades for our Ninja smoothie maker. At first the WERE great. Then around the time that the return period was ending, we began to have problems. Literally the day that the return period ended. My wife was making a strawberry smoothie and noticed there there was a small amount that had leaked out onto the base. As always, the first thing I checked was if "operator error" was involved. We looked at the rubber gasket and to see if we had not tightened the blade into the cup. There did not appear to be any problems with the gasket or tightness. We tried again after washing everything out. Then we made a real mess. Strawberry and cream leaked everywhere!I was examining the blade and noticed that the rod that attaches the blades to the fins that connect to the base and allow the unit to blend was going up and down about half an inch. That could be the only reason that the liquid was spilling out. No crack in the unit or the cup, no problem with the gasket, no problems with the base. We tried the original Ninja blade base and it ran perfectly with no spill. Again, I tried the AxPower blade base with water and sure enough, the water leaked out. I put more water into the cup and pushed and pulled on the bottom section with the fins and again water leaked out.So, as I said, the return window had closed so I reached out to the seller to see if there was any troubleshooting that could be done. I did not want to try anything that would further damage the item without guidance. Well two messages to the seller 7 days apart and NOTHING. My messages still sit there unanswered. Perhaps my experience is unique and we just got a defective lot. I can only go with my experience however and it was terrible.I would not recommend this product to anyone. Seems like a design flaw that is not present on the original Ninja blades. As much as I like a bargain and as much luck as I have had with other replacement parts the adage, "You get what you pay for, seems operative, though I spend about 28 dollars and have nothing in this case.

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.

Somehow we lost our original blades so we bought these as a replacement and they have worked great! We've been using them for quit some time (maybe a yearish) and have no complaints.

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.

The seal on lid oration of these cups are terrible; and yes, I’ve used the extras plastic rings provided too. I have to keep a towel next to the blender for the eruption of milkshakes that regularly escape. I have had this happen with varying amounts of shake; it’s not an overfill issue, is a poor quality problem. The blender is used daily but I should get more than a couple of months out of the two new blender bases.

This is a great replacement for the original that stopped working and is nowhere to be found on ninja site. I use my blender often to make shakes and salsas, so was heartbroken when I saw ninja didn’t sell that part. I decided to check Amazon and found these. I was hesitant at first because it wasn’t an original part and because of some of the reviews. I decided to give it a try and I’m glad I did. I haven’t experienced any leaking like some reviews mention and the blades have held up well. They work wonderfully and are a great value since two come in each pack.

This is a good replacement blade for your ninja blender cups and at an affordable price too. Worked perfectly for my bender.

It fits with my nutri ninja model BL480UK 30 and worked well. Happy with the product.

Got 2 replacement blades, 1 with low quality silicon top, that we are not sure will work for long time and 1 without the 7 fins part. Amazon paid us back quickly, but that won’t solve the fact we need to find and wait for a new replacement part

The original blades broke down. So instead of buying a new device I was able to find and buy these parts.

beide Aufsätze waren nach 6 Wochen undicht. Rosten innen, geben den Rostgeschmack ins Innere des Behälters ab, verdrecken das ganze Gerät. Schrott!!! Finger weg.
