Love my spare ninja 16 oz single serve cups. They work perfectly with the QB 3000SS blender that I recently bought. Convenient to have extra cups for everyday use. Glad they were available at Best Buy.

Haven't used it. Just know that the lids aren't sealed which is not great if you want to use this to go.

We have several Ninjas and these work with all the different units and the tops and blades are all interchangeable. My wife and I each have a single serve Ninja at work and the Large unit at home. The sealable lids allow us to put all ingredients in the cups at home, take to work, pull out of fridge at lunch add a little ice and throw it on the ninja when we are ready. We can also make up a few and take already made up to the sister-in-laws lake house and they work on her Ninja as well. Hold up great in the dishwasher and even handle drops well. (oops)

product does not leak, easy to clean and one cup serving perfect size.

My Ninja blender (BL 770 series) came with two single serve cups, but that was not enough for our family. I wasn't positive that these were the right ones, but fortunately they were. Now we can all enjoy individual smoothies!
