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.

Works amazingly

I love that it sticks to my counter, since it blends hard and efficiently. It is big enough to blend a good size smoothly. Easy to clean and like the extra attachment to drink right out of it. Glad I made this purchase

Beautiful style and color

Very nice blender for making my morning protein shakes. I love how easily the base screws onto the cup. I don't think this one will ever leak. The purple color is what sold me. I highly recommend.

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.

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!

Strong blender

Strong blender, so far I've only used the smoothie feature and then pulse to clean after. I really like how smooth the smoothies come out. I do think it should come with an additional tumbler though and I am very upset that they stupidly put a huge sticker on the tumbler that is impossible to get all the stickiness off. I tried scrubbing it with a sponge and it completely messed up the textured lines on the tumbler. I'd buy another tumbler if they had it in stock in the pink peppercorn but they don't and only if they didn't put that sticker on it!

LOVE IT but.....

My best friend got me this blender for Xmas and I LOVE IT - but I do have two complaints. While the blender is fairly easy to clean, I am somehow getting smoothie particles in the handle of the blender. I don't see how this is possible as the handle is completely sealed off from the cup. I honestly wouldn't even care about the smoothie getting in the handle if it was possible for me to clean it out :( ALSO - I know it is not mold and my smoothies typically consist of spinach and blueberry, hence the dark color. My only other complaint is that the replacement cups are so expensive!

Pretty but mold prone product design

After two washes and one use mold has started to grow inside the hallow handle. There is a thin opening where the top of the handle meets the tumbler that isn't sealed where water gets inside and is trapped. The handle cannot be removed to wash, wipe out, or dry. Very disappointing design flaw because I like the product but cannot fathom drinking from a moldy vessel and I only imagine the issue worsening overtime as more water seeps through. Please consider redesigning the tumbler with a solid handle instead. Otherwise the motor is powerful and blades are sharp enough to make smooth consistent drinks with lots of frozen ingredients. Proceed with caution.
