Blender Cups Fit for Ninja, Replacement Parts 18OZ Cups with Sip & Seal Lids, Blender Accessories Compatible with Nutri Ninja Auto IQ Series BL480 BL481 BL482 BL490 BL640 BL680 BL450 BL482(2 Pack)

THESE ARE PERFECT for the Nutri-Ninja BL455 !!! The problem is none of these cups on here list the 455 and the few that do are mostly not correct. Here is the difference that I had to research: My 1000 Watt Ninja blades screw into the inside of the cup, while the 600 and 900 watt Ninjas screw on the OUTSIDE of the cup!!! These cups are a GREAT DEAL, seem like a good quality and durable, and also everything fits good and doesn't leak. If your Ninja blades screw inside the cup, then GET THESE HUGE 32 oz cups! You won't regret it! :)

These fit great on my nutri ninja blender base. Thank you! And the tops work better than a straw, I like them alot. Now I can make my own smoothies at home.

Exactly what I was looking for! Needed a replacement, couldn't find anywhere near me, love my ninja!

Works great. I'm also aware my ninja blender is powerful so I use the blade gradually pulse action. The ninja is extremely powerful so just a shot or two at a time works great for me.

Time will tell. Not a great design by ninja and eventually they all lose seal. That said, we use them all the time and no product with moving parts and a seal lasts forever.

Bought these for my Nutri Pro BN401. They work perfect. Fit the machine perfect with no leaks. I love that they are a little shorter so it's easier to eat my thicker blends out of. I don't use the lids to drink out of since I don't take these on the go with me so I can't say anything about those. These are the perfect size for my needs. Very happy with them.

I see that someone named Ryan wrote a review stating the device dripped a foul manufacturing residue. And that the device also leaked beverage from the vessel. This is true with me, too.Also, the blade wobbles severely, as if a bushing or seal is missing.This is the most poorly manufactured piece I have seen in my life.I don't know what the brown/black machining residue is that drips from the piece, but it shouldn't be anywhere near food.Do not buy this.

The Blender Cups for Ninja Blender (18OZ Cup with Sip & Seal) are incredibly high quality – really durable and works great with my blender. However, I’m not a huge fan of the cap. It’s functional, but it doesn't quite meet my expectations in terms of ease of use. Despite that, the cup itself is excellent and definitely worth it for its overall quality.
