5-piece Ninja Blender Cups Replacement Single Serve 16oz Cups with Sip & Seal Lids, 6 Fins Extractor Blade Compatible with Nurti Ninja Blenders Pro BL660 BL663 BL663CO BL665Q BL740 BL770

Goes well with the ninja blender. I bought it to blend batches of baby food. Quite powerful and gets the job done. Very easy to clean if you clean right away. The lid locks on tight to the blender. I like that I was able to save a little by buying these instead of the brand one.

This was a great replacement for our broken cup. It works just as well as the original. The original lids are interchangeable. We haven't had any leakage so far with near daily usage for about 2 months.

Great for multiple people making smoothies in the same house

I am not afraid to buy Aftermarket- non original manufacturer parts for repair replacement because it often saves a lot of money. And now a days, manufacturing is a uniform, high quality, robot controlled process. But unfortunately this product is a big fail. I guess I won’t be able to get my money back- but will need to source new parts from the original manufacturer. This aftermarket blade base for the Ninja blender began making noise about a month after using it. And it leaks in the base itself. By comparison, the original blade base lasted for many years, before cracking due to being dropped accidentally.

I have had my ninja blender for over 7 years so I don't know what model I have. I ordered this set thinking it would work with my blender. The cups fit great and attach without any problems to my original blade. However, the blade does not work with my blender (the blades look the same as the advertised ones, but the bottom part that fits into the blender is shaped differently. This is not the fault of the product, I just didn't have the correct one for my blender. It is nice to have extra cups and lids, they appear to be made of the same quality as my original set.

Came fast and it works on my Ninja!

These work perfectly with out Ninja blender. They are a perfect accessory for a single portion.

The lids arrived grey, in case you are looking for black, it doesn’t matter to me. Functions the same as the manufacture original. No leaks. Blender part works perfectly (can’t tell apart from OMP). Impressed.
