Easy smoothies

We love our Ninja BlendBOSS. It is easy to use and to clean, and it works well. We finally have a blender that actually blends ice and frozen fruit so we can enjoy smoothies.

Love the purple

Versatile Blender

Love everything about this. The colour is a great feature but love the how versatile this is along with not being bulky. It looks appealing too left on the counter.

Best blender I’ve ever had, very happy.

Grinds seeds up so well, very powerful. It is not noisy considering how powerful it is

Saved my mornings!

I’ve had this for a few weeks and I love it. My old small smoothie blender was underpowered and couldn’t handle ice or frozen fruit. This thing whips up my morning smoothie and my evening frozen margarita without ever stalling. Easy to clean also. Love the no gaskets design.

Cute and easy to clean

This is the BEST blender.. I had the nurtibullet before this and this is by far so much better. It’s quieter and easier to clean. We’re also able to use the cup!! So less dishes!! I love how you’re able to just blend and go.. a lot easier. And the color is just so darn cute

Great product!

I love everything about this blender EXCEPT, I would love to be able to purchase additional tumblers. Hopefully these will become available ASAP! Will rate it 5 stars once that is possible!

Water accumulation inside the handle

After only two uses (both hand-washed), water has already accumulated inside the handle, which is clearly a design flaw. Since the handle can't be opened to dry or clean it, I'm concerned it will eventually develop mold. The blender itself works great, but for a premium-priced product from such a well-known brand, these issues are unacceptable. Very disappointing.

Nope, do not buy.

I was so excited for this product by unfortunately it ruins my morning. It doesn’t blend my smoothie all the way, so i have to scrape it and redo it. And also it is so incredibly hard to close all the way, and to open it, forget about it. It makes my hands every time. Would not recommend to anyone. DO NOT BUY
