It works well. I gave it. 3 stars because I would love to be able to get a larger tumbler for it. The only other tumblers to buy are actually smaller. A 32 oz would be great.

I use it every day! SO handy and compact but powerful!! Worth the money! It is fast and easy to use and to clean. The flexible bottom on the straw makes traveling with it SO easy!

Coming from a college student, this is the best purchase! Perfect for on the go, stores so easily, blends in seconds, and i’ve gotten so many compliments on the cup!

The ninja blend boss is easy to use and a great help making delicious healthy smoothies. I tried to buy more tumblers but they are out of stock. I think it's easier with more than one so you don't have to keep cleaning the one out.

I love it!! It suctions to the surface!!! I was a little confused with the instructions at first, until I read them while making my first smoothie! The concept is perfect and works great. I can’t wait to use it more!!

Ordered. Never Opened. Returned. Waiting on a better sale to get one. I have the old outdated version But it still works Perfectly so unless this one quits or the sale price be pricing I will continue with the one I have. But if you want a good one I have heard great things about it. Can't go wrong with a Ninja …. That why I'm still rocking with the old version.

[This review was collected as part of a promotion.] This ninja blender is so nice and easy to use! It’s lightweight and doesn’t take too much space. Looks cute on the counter too. Makes really nice smoothies and blends easily into a good consistency. Seems durable and easy to clean, maintain!

[This review was collected as part of a promotion.] I love the settings on the ninja. Our family loves making smoothies and crushed ice..awesome that this does both (and more)! The grooves around the blender blades are not as deep as my precious Ninja Bullets, therefore, easier to clean after use. My only complain is the color. I am not a fan of green and pink together..however my 10 year old says the colors slay and my 5 year says the colors are beautiful..so I think that's just me!

[This review was collected as part of a promotion.] Ninja BlendBOSS Tumbler blender in the Watermelon Bubble Gum design is super cute💗The blender came nicely packaged with no damage. The Ninja blender has AUTO-iQ using time blending and pausing for the perfect output! Make sure that you follow the instructions as it indicates for best results, allow programs to run until it’s complete, which is usually one minute. This came with a quick start guide that was very easy to follow. The blender is very powerful and very loud as expected. The base of the blender has suction cups to keep it stationary on the kitchen counter. It has four modes of blending. I love the fact that the blender container converts into a to-go cup!

I received this little power house about three weeks ago and using it daily. It only gets better. If they offered ten stars, I’d give it TEN STARS!! It pulverizes all the frozen fruit I use for my smoothies. I rested the ice crusher. They weren’t kidding…it made snow. Had my family over and my son and his wife were so impressed, he ordered one right then and there. The tumbler is great because make you take it with you without having to transfer it. I own a Vitamix and Blendtec 525. Super powerful but I like this so much better!!! All in all……MY HUSBAND AND I LOVE THIS!!!!!
