16oz Replacement Cups for Ninja QB3001SS Fit Compact Personal Blender, Single Serve 16-Ounce Cup Set for Ninja BL770 BL780 BL660 Professional Blender, with Seal Lids- 2 Pack

Works well as a replacement cup for our ninja to make shakes - fits well, does not leak. I like having a few of these around so I an make several shakes for the day or for others. If you need to replace your original ninja shake cup don't hesitate on this item.

VERY NICE replacement cups! Much nicer than the cups that come with the original purchase of the blender! These are thicker, more durable, and have much nicer lids. I just received them today, but have already used one. The original blending lid screwed right on and fits perfectly as well. I also feel that these cups make the blender seem a little quieter too. (Which, this is one of the LOUDEST blenders I’ve ever heard!!) overall, I am happy with this purchase!

Good quality works.Great, nice. Seal on the lid.

They work for my model quite well. The cap is good

These fit perfectly. They work exactly as intended. The cutter assembly does not leak when blending items. They are a great addition or replacement to the original supplies that came with the ninja blender. I would buy these again

Better than the original equipment cups. Better measurement scale, much better closure on caps. Only tiny negative is that the screwcap blade assembly needs a bit of fiddling to fit on properly.

Good quality and fits perfect!

Great substitute. I stupidly put mine in the dishwasher and it warped to a little melted shape.So do not put these in the dishwasher
