24 oz Cups, Compatible with BL480, BL490, BL640, BL680 for Nutri Ninja Auto IQ Series Blenders (Pack of 2)

This cup is not from Ninja. There is no ninja graphics on it. It weighs significantly less than the cup that came with my machine, a difference of nearly an ounce. That doesn't seem like much but its more than a 20% difference, which is significant to me. One cup MOSTLY fits into the machine and the other mostly DOESN'T fit. I have to screw on the blade really really tight and push down really really hard to get them to click into place. One cup is a little easier than the other. In any case I don't want to grind parts and wear out gaskets and fins. I bought this for the BL681a model from Sams Club.

Works perfectly with the ninja, great replacements, would buy again. Just look at your model number and make sure it's listed and all is well.

bought this item since I wanted to have some backup cups when doing extra smoothies but they are too big for my Ninja blender.out of that the quality is great, i use them as regular cups.

Exact same as the ones that came with my Ninja auto-IQ blender, except they don’t have the “ninja” brand stamp. Exact same as higher priced ones from other Amazon listings like: 24 oz Cups for Nutri Ninja Pro Replacement Cups with Sip & Seal Lid, Compatible with BL450 BL454 BL456, BL480, BL490, BL640, BL642, BL680 BL687 for Nutri Ninja Auto IQ Series Blenders (Pack of 2)

Came with two different styles of lids. Unfortunately neither has a vent hole and makes the pour slow. Otherwise very good quality.

Was hesitant to purchase these considering the reviews but they are excellent. I have the BL450 and they fit perfect with the blade attachment and the original lids. I would buy again!

Great cups. I use them every morning for smoothies. I wanted extra cups so I didn’t have to wash them after every meal. They are perfectly compatible with my Ninja blender. Would recommend.
