Love It!

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 💯😁❤️

Great blender! Where is my straw?

I just bought this from a retailer in Canada and I love it. The only thing I don't love is that colour choice was nonexistent at the store. They only had one and now I realize that my tumbler did not come with the new straw! Why do some people get a straw and others don't? Why can't I buy a second tumbler for this? Seems unfair that some people are getting more than others. Other than that, it's an awesome little blender. I put it on a rubber pad to make it less noisy while blending and so far, it's been awesome. Would be even better with a straw and extra tumbler though.

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.

Full blades

Very cute but as soon as I got it I could tell the blades were dull bc of the smell it releases when it's mixing

Stylish, effective, almost perfect!

[This review was collected as part of a promotion.] I’ve been using the Ninja Blend Boss for a few weeks now, and overall, I’m really happy with it. It works exactly the way it promises: blend, pop off the base, add the drinking lid, and go. No transferring to another cup, no extra dishes — which is a huge win for busy mornings. The blending performance is genuinely impressive for a compact system. The preset modes (Blend, Smoothie, Ice Crush, and Pulse) are intuitive and actually make a difference depending on what you’re mixing. I’ve thrown leafy greens, frozen fruit, and nut butter into it, and it handles everything without a problem. What really sets this apart from similar bullet-style blenders is the design. The cup feels trendy, reusable, and surprisingly durable — something you’d actually want to carry around, not hide in the fridge or tote bag. My one complaint is the lid setup. It only comes with a sip-style top, which works — but I wish it also included a screw-on spout cap or a more secure button lid. I haven’t dropped it (yet), but it definitely feels like that could get messy. Having a leak-proof option would make this truly portable.

Practical & Wicked!

[This review was collected as part of a promotion.] I love this ninja tumbler blender so much! It’s perfect for traveling on the go without having to worry about transferring your drink to another cup! It’s super practical and my smoothies always turn out great! I absolutely adore the color too because it reminds me of WICKED! 10/10

In love wish it had more accessories

I love my new blender. I bought it in lilac. I leave it at work and receive compliments all the time. My only issue is I wish there was an option for a smaller cup size and a straw. At times I don’t want a 26 oz beverage , but if I do I would like a straw. “ I’m a lady !”. Lol. Ninja If you decide to make those accessories . 5 Stars. And hit me uup!

Blend Like A Boss

[This review was collected as part of a promotion.] Blend like a boss with the Ninja BlendBoss Ice Crushing Tumbler Blender. It quickly turns ice into snow in a few seconds. This powerful blender makes great smoothies that you can take on the go. The 26 ounce cup comes with a leakproof locking lid with an easy to sip spout. This blender is super easy to use and takes up very little space making it great for small spaces. It is a bit noisy but that’s to he expected with 1200 watt motor. Very good at blending frozen fruit. Instruction guide is easy to read. I love the fun colors it comes in.

Brilliant blender! Such smart design.

[This review was collected as part of a promotion.] I’ve been using it for about a week now, and I’m honestly obsessed. It’s powerful enough to crush ice and frozen fruit in seconds, but what really sets it apart is the convenience. The blending cup doubles as a to-go cup I just pop the lid on and head out the door. It fits perfectly in my car’s cup holder (which never happens with other blenders!), so I can actually enjoy my smoothie on the go without making a mess. It’s not as loud as other blenders either so you won’t wake your family at 4am. Cleanup is super quick too just rinse and go. If you’re big on smoothies, protein shakes, or even iced coffee blends, this little blender makes it so easy to stay consistent. This will make the perfect Christmas gift! Side note: I had also been using it to blend and purée while cooking,

Cute and works great!

[This review was collected as part of a promotion.] This adorable blender looks so good on my counter and even better…it works too! I’ve made salsa in it and tonight I made myself a smoothie with banana fudge ice cream, milk, half a banana and a few maraschino cherries! It was perfection and I cannot wait to keep using this fantastic, easy to use blender! Love the look of it and the efficiency! Thank you!
