16oz Blender Cup Set for Ninja Replacement Parts - Single Serve Cup with Lid and Seal Lid - Compatible with Nutri Ninja Series BL770 BL780 BL660 BL740 BL810 Blenders Review

These mugs are exactly what I was looking for, but if you're expecting Ninja branded lids, these are obviously not included. They come with lids but not Ninja branded lids.

These things are great, the lids close well, the lid latches properly and stays open when you fold it all the way down like it should. I'm glad I bought these instead of the cheaper and crappy versions.

I have original cups, they work perfectly. I've used these smoothie cups, no leaking due to the thicker liquid. I then used it for a protein shake and it went in my bag, I made sure it was safe and even swapped out the lid for a different one. It kept flowing from the edges. Super disappointed.

When I ordered these parts I got an unmarked lid and two mugs, but instead of two more sealed lids I got a replacement blade. I'm giving 3 stars because the lids are at least adequate (drink holders are a great invention) and I think it's a good idea to have an extra blade in case anything happens to the original.

I like the extra cups and flip top lid, but the flip top lid doesn't close completely. The screw cap has a rubber seal and won't leak, but the part you flip up to drink doesn't provide a seal. When I put a bottle in my lunch bag, there's usually some cocktail left in the bag before work. I wish the flip top had something better than a plastic gasket and was watertight. I'm also very happy about the additional cups and details.
