Ninja Blenders-Accessories, 24 oz, Stainless Steel

I’m a teacher. I bought this to keep the ugliness of my shakes and smoothies away from the public eye (students AND colleagues). Every time someone sees a green shake. I feel there’s questions that start, judgement, or just plain “Eeeeewww! That looks gross!” — either stated out loud or in their minds via their face. In got tired of that in the past and normally would then stop my regimen.This keeps your drink and your personal goals your business.The cups are sturdy! I put them in my backpack. They stay cold for wire and not (especially if you have ice or frozen ingredients in your smoothie). This helps big you need to drink a smoothie later in the day.I purchased them (I bought 2) with silicone reusable smoothie/boba straws. As soon as I’m done, I push the straw in to the cup — no fuss no muss.This purchase has helped me to keep me on track with my program and goals when I’m out and about (work and on the weekends). Totally worth it.

Two words... BEST PURCHASE EVER!I absolutely love my nutri ninja and use it multiple times per day. It is amazing. I wanted to see if this cup would make a big difference with my morning shake. Let me tell you it does!!! It does an amazing job of keeping my ice cold drink nice and ice cold! Imagine that?!? This cup does it's job beautifully! It is dishwasher safe and seemingly very durable. Go ahead and give this a try! I think you will LOVE it!!!

Replaces the plastic one which came with the unit. We prefer stainless over plastic.

I've recently adopted a plant based diet, and I love to make a smoothie to take to work for breakfast. I used to use the cup that comes with the ninja, but one day when I was running for the bus the smoothie spilled out of the mouthpiece since there's no cap. And, the smoothie never stayed cold. That's where this cup comes in. I LOVE it!! It holds a ton, keeps my smoothie cold, had a lid, and is really easy to clean! This cup has been a game changer, and I highly recommend it!

I ordered this because the drink size containers disappeared for both my Ninja blenders, the predecessors to the current models. This does fit the blade but it and the clear plastic blender cups I also bought leak when blending the standard way.The cup is nice and beefy and is indeed insulated. The vendor shipped super quick and I received the cup in original packing with inserts. I can make it work by blending upside down. That is, I slot the cup into the blender, turn the coupled pair upside down and press downward. The blades are easier to come off this way and it doesn't leak. Being able to blend a hot beverage directly into an insulated carrier makes it worth the extra effort.

I purchased this item because I recently bought the Nutri Ninja's Ninja Blender Duo with Auto IQ 1500 Watt, Model BL642, and this item was not included. I always knew I wanted this accessory because it claimed to keep drinks cold, and it also offered the convenience of drinking directly from it. Well, so far, I have only blended drinks using this cup, I haven't used the other cups the package came with, and I absolutely love it. I usually wind up mixing organic fruits and veggies, such as, bananas, frozen blueberries, frozen raspberries, frozen strawberries, kiwi, tomatoes, frozen/fresh kale, frozen/fresh spinach, and frozen sweet potatoes along with evaporated milk/almond milk...and it does a fabulous job of keeping my concoction cold even though I might take an hour or two drinking it.

This cup works fine and will keep a smoothie from completely melting to liquid for about an hour so it's probably better than the regular plastic containers. But while this is double-walled stainless steel, it is not actually insulated aside from the air between the two stainless steel layers. When I make or pour in a smoothie the outside of the container is cold within 60sec showing that there is little to no actual insulating properties. If you have a hydroflask or any of the other brands of VUCUUM sealed double-walled containers you know that you can put hot or cold beverages in and never feel it on the outside. The vacuum between the layers is the key there - without air molecules in that space to transfer the heat or cold the contents are very well insulated. To be fair - it isn't advertised as vacuum sealed but you might assume that when you see that it is double-walled stainless steel.

Great product and very durable. The stainless steal double walls make this product very durable and even the plastic portion and lid are pretty beefy. I can see these cups lasting for years to come. However, on the bottom of the cups there is a warning that these are not to be used to blend hot liquids. Personally, I don't see myself doing that anyway. This product is well worth the money and I give it 5 stars, because this is what customers like myself generally look for in a quality products. But, I give "Fufilled by Amazon" one star because they sent me two plastic version of this product and charged me for the full price of the stainless steel cups. I contacted "Exclusive Bulbs" and they immediately corrected the issue and rushed out to me the stainless steel cups I originally ordered. Thank you Exclusive Bulbs for making things right!
