Better option

I like the ninja boss blender. I want to buy it but I would like for it to have a stainless steel cup made just for that blender, So my smoothies can stay colder.Longer. If that was an option with that, I will actually consider buying a new blender And extra cups.
I would recommend this to a friend!

Nice blender!

I have a few Ninja blenders and this one is my favorite. Due to the size of the tumbler and ease of transitioning from blender to usable tumbler. It is also larger than what I have and holds more liquid as well as being visually aesthetic.

LOVE IT but.....
on March 3, 2026

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!

I received my Blend Boss last Sunday! I took a smoothie to work for. an entire week 😂. I laugh because I am at work at 5am and to be able to take a smoothie daily is amazing! It’s that easy 🙌🏽. Easy to make, clean up and off I go! Real talk, I love this blender and I am getting healthy as I go! Skin looking better in one week 💯😁❤️
