Pros - 1. works well with the blender, 2. Blender noise is down significantly (which was the reason for buying a new blade).Things to keep in mind -1. The base of the blade looks different than the original blade (depth of fin is different), but it fits perfect with the blender, 2. The extra rubber ring that came with this item is nice but removing the rubber ring from blade for frequent cleaning is not easy. You need a special tool to take out the ring from the blade, 3. This extra ring will NOT fit well in your original blade. If you try to put the new rubber ring in original blade, the lead of juicer cup will not close fully and it will leak. So, if you plan to use the new ring with the old blade, be mindful of that.Otherwise the blade looks very sturdy. I would not be make any comments about the durability and this point because I started using a couple of days ago. I hope the company include a small tool to help remove the ring from the blade for periodic cleaning. Otherwise this is a good product.

There's a lot of direct from China garbage on Amazon these days, but this is is not one of them. The bearings wore out on my OEM blades, and I didn't want to pay Ninja's absurd replacement cost that's 50% the price of a new blender as the blender works great still.I was lured in by the claim that the blades are thicker than other knock-offs, and I'd say it's true. They seem comparable to the OEM blades, the fit is snug, and the thread match well. Even came with a spare o-ring. I use it almost daily and couldn't be happier.ps if you've never tried a smoothie made with 1 banana, 1 cup frozen spinach, 1 scoop protein powder, and a red bull, you're missing out.

I wish there is a "zero" star for this product review. I purchased it few months ago during winter time and I haven't used it much during that time. However I have used couple of times and smelled like rubber burning from the base so I thought my blender motor base was burning and I was about to throw it away since warranty period was expired. But just before I toss it away, I wanted to confirm it once more so I switched my sister's blade and used in my blender (she has same Ninja auto IQ) and there was no smell and it was just fine. As you can see from the pic, my blade that I purchased from this vendor, the bottom rubber got melted so badly and the burning smell was coming from this blade not from my blender motor. This replacement is NO GOOD so do not buy this vendor.

Love my replacement blades for my Ninja. I previously ordered a replacement from someone else before and had bad luck with it, it was making my motor overwork itself. I decided to give this one a try and I’m glad I did. I use it about 8-12 times a week, i make a green juice with it but the real task comes with my post workout shake; I use a frozen banana, raw almonds and hemp seed in my chocolate protein shake and the blades are still working great( almost 2 months using it so far). Great product!!!

While it works well, after consistent use (3 times a week at least) it began to leak and cracks in the plastic became evident.The product remains usable, but now you have to be more careful about cleaning regularly and I am not sure how much longer it can realistically last.

I have a Nutri Ninja Professional 900 Watt BL456. I used the original blade for about 6 months and it is fine but wanted a second one for convenience. The order was processed quickly and the replacement product was delivered on time. I have used this replacement blade almost daily for the past six weeks and it works great. The socket fitting is a slightly different design from the original. It fits properly and functions as expected - no compatibility issues whatsoever.

I purchased this product when I needed to replace the gasket on my Ninja blade assembly due to mold. I decided to go ahead and order the extra assembly with the gaskets just to have a spare. The gaskets did not always prevents leaking with my Ninja parts, although sometimes they worked fine. Over time I ended up using this blade assembly most of the time because it didn't leak. Unfortunately, as others have noted, the rubber fins eventually deteriorated and broke off. I didn't notice a burning smell, but it became very loud during blending. When I didn't use it for a day or 2, it seized up, although I was able to oil it and get the blade moving again. I just didn't realize what was happening or i would have stopped using it. I bought this a lottle over a year agao, and considering my usage, I'd say it was fine for about a year of nearly daily use. That said, I'm disappointed. I don't want to replace stuff annually.

Update May 10 2021. Ok, so they worked fine. Today I smelled burning rubber and this happens.My original blades were leaking around the rotating mechanism. I ordered this replacement part and my Ninja blender works like new. I have not realized that my old Ninja blades were probably already dull because I can see the difference how much better my blender works now. I have used the new part for the last couple of weeks, everything fits perfect and material is sturdy. No more leaks either..

High quality product, great customer service and fast response from the support staff.

I'd lost the original so was delighted to find this

fits perfectly into my blender. hight quality blade.

Very poor quality. With the first use the fins were torn.

Works well no issues.
