16 oz Cups Set with 2 Seal Lids Single Serve for BL770 BL780 BL660 Professional Blender, Clear Single Serve Cup and Lid (Pack of 2)

I use these almost every day for the past couple of months and love them! The cups are super durable and fit perfectly with my Ninja blender system (model BL770). The seal lid with the flip top DOES leak when you’re shaking liquid or if it turns over, but it’s not terrible enough not to use it in the car or on the go….just beware. But overall, these are great replacements!

While the tops are a little weird in this kit, the bottles themselves work amazingly! The o-rings seal just fine and they seem to hold up well in the dishwasher. I'm happy I found these since I had a hard time finding the right bottles for my blender since the model number seems to be all over the place but, for anyone with the same one, it works great!

I own the Ninja Fit Personal Blender that came with two 16 oz cups, each with a sip and seal lid (the lid that has a little flap that snaps closed to keep anything from coming out when not drinking from it). The confusing thing about this item, at least at the time of this review and the time of my purchase, is that the listing SAYS "2 sip and seal lids" but shows one sip/seal lid and one lid with a sip opening but no seal flap. And that's what you get. One of each. That was fine for my uses. I keep the no seal lid at home when I can just plop a straw in and drink. I use the sealing lid when taking my smoothie to work and wanting to avoid spills. Been using these ones for a month now and they fit just as well as the originals that came with my Ninja, lids seal just as well. They wash up fine in top of dishwasher. If you need a few extras, this is the way to go.

The only reason I took off one star was because the lids are so hard to get off. I’m these are not original ninja cups, but they work. They fit perfect with blade, no leaking, just a pain to get the kids off. Use a jar opener if needed. Other then that, no complaints

Great ninja cups. I have a large nutritional ninja and wanted som cups with lids to drink from so as to not use straws. Thse are a great item and the material is super durable and thick.

Product is as described. I needed extra cups and these were a good price and perfect fit. My protein smoothies will taste great in them! :)

The cups fit perfectly with our Ninja. Everyone has been drinking smoothies while at home during Covid and we needed the extra cups. I will defiantly buy more if we need them.

It was great to be able to order two additional 16 oz. cups for the Ninja blender especially one with an enclosed flip-top lid.
