Blender Cups for Ninja Blender, 24OZ Cup with Sip & Seal Lids, Compatible with Nutri Ninja Auto IQ Series Blenders BL450 BL454 BL456, BL480, BL490, BL640, BL642, BL680 BL687 (2 Pcs)

So far these cups held up, I wouldn’t recommend putting in the dishwasher. I purchased a set on eBay and the top warped not allowing for me to screw on the blade. After that experience I turned to Amazon but I have not risked putting in the dishwasher. Play it safe and hand wash they will hold up! I’m happy with the purchase and price

Beware! I Received product and 1 of them is used and dirty. You can see the difference between the two in the pictures (2 pics of the used cup, 1 of the new one). I'm happy with the other it is as advertised. I will say the lids kinda suck as other reviewers have indicated, they don't snap closed like the original ones but it's not a deal breaker for me and at least they both appeared new.UPDATE - Can I give them no stars? Sent message to seller and NO RESPONSE. So my only option is to waste my time sending back both cups and then what? Seller - You SUCK. Amazon - Not much better, thanks for wasting my time.

I purchased these so I could make to-go cups and then just pop on the NINJA when I need it... They work GREAT - no leaks and the bonus is, the drink top. I will purchase more...

Advertised as extra cups for nutraninja however they are not the correct size.

Perfect for my smoothies as the originals are in the dishwasher. And these have measurement markings on them.

I only received 1 instead of 2 as advertised. The other part of the box was filled with bubble wrap. With the holidays, I got to busy to send it back. So, 1 cost me $18+. Not a good buy and not a happy customer. :(

Very easy to clean and helped me build up my Smoothie cups

Works great
