Blender Replacement Parts for Ninja, 24oz Ninja Blender Cups with To-Go Lids, Compatible with Nutri Ninja Auto iQ Blenders BL2012 BN801 BL480-30 BL640-30 BL642-30 NN100-30 BL450 BL456

Seem authentic with slight differences from my originals that came with my blender. The clear has a slight tint, and the lids are black instead of gray but everything cross fits each other and feels high quality. I don't use a dishwasher so I can't attest to their survivability in that regard, but I would expect them to handle it well. Probably will purchase another set, just wish they were a little cheaper.

Arrived on time and work perfectly for our Ninja. It is very important that you know how many plastic points come out of your Ninja to get the right one. This one fits our machine perfectly and came in on time.

Ordered these to have extras for my NINJA mutli-blender. They are nearly identical to genuine NINJA-branded product - they just don't say NINJA. Seem to be essentially the same quality as the original, but at a better price than OEM.

Durability could be better. These lasted a couple years before the plastic ledges broke off and they weren’t usable in the blender anymore. See picture. One cup had one plastic extension break off and the other cup had three plastic extensions break off. I don’t know if it was the heat from the dishwasher or what they worked great for a while but now it’s really hard to use because the blender requires a plastic nub to be in a specific position in order to operate.

These are technically the correct cups for my Ninja, but the mouth and the threads are not sized right so to make them work you have to crank them down really tight so hard my wife can't do it herself. It gets worse after blending its even harder to get off so that I have to use a rubber band to get enough grip to remove it. I've stopped using the new pair and just use the old cup for both of us.

I was looking for two new smoothie cups when I came across these. It works great with my Ninja smoothie blender. A few features to call out...unlike my original cups, these did not come with a mark for 8 oz and its hard to clean by hand the inside bottom of the cup. The upside? The price and I like the cup lid. It only has an opening to drink from. It works.

Just as good as the originals that came with the Ninja. If you have a dishwasher with a heating element, don't put these in it. If you have a dishwasher that using convection drying, like our new Bosch, you're good to go using it for these. Our old Kitchen Aid dishwasher melted all of our original cups into ovals.

I will enjoy making my drinks in these.
