[This review was collected as part of a promotion.] I have had a Vitamix blender for the past 12 years that I have used almost daily. This helps set the standard for what I'm comparing this blender too. Our family makes smoothies almost every single day and uses our blender for other things like soups, dips, protein drinks, etc. we are a family of six and so we tend to make things in large batches, however, I was curious about the single serve blender because there are times where I take something to work and thought this might be a good tool for pulling that off. The blender did a good job when I thought through what was actually going to happen. Let me explain. With my typical blender I just throw everything in turn it on and we're good to go. But with this single serve ninja I had to be very conscious about how I was going to actually blend because of the important fact that you tip the tumbler upside down for things to blend. As an example, I made a protein shake where I dumped the protein powder in the bottom of the tumbler and then poured milk on top. Top. Mistake, because when I put on the blending top and then tipped it over the blades are now on the bottom but all of the stuff I wanted to blend was at the top. The milk came down however a lot of the protein powder got stuck at the top and there was no way for it to get down without taking off the tumbler shaking it around a little bit then trying again. I ran into the same problem yet slightly different when making a smoothie. We tend to use frozen fruit with our smoothie and what I did was I poured in kefir, then added all of my frozen fruits and coconut oil. But again, because this blender has you tip it upside down to blend a lot of the stuff got stuck and there was no way to get it down to the blades. I would have to take the tumbler off shake things down a little bit use a fork to get things unstuck and then blend again. Order of operations with this blender and thinking through what's going to happen is important. You can't just throw everything in and expect it to do well, unless you're blending only liquids that flow easily. We want to be able to just throw everything in turn it on and it blends everything and this is just not that blender. All that being said, when the blender works it works. Switching to the drinking top. It stayed liquid tight and I never had any leaks. Everything was really easy to clean and it's nice that you could just throw it in the dishwasher. One last thing that is both a pro and a con are the suction cups on the bottom. It's great during blending but it just makes it hard to move the base around if you want to pull it out from underneath your cabinet blend and then push it back under the cabinet for storage. The suction cups had a lot of sticking power and I just worry over time they are going to break. Overall, it's actually a really good blender, it's just not the blender for how our family uses blenders.

[This review was collected as part of a promotion.] Thanks to Influenster and Ninja, I got the wonderful opportunity to try out this product for free in exchange for my honest review. I was so excited to try out this blender because I was in need of one for travel. Not only is it extremely useful, the packaging is so adorable. I love it! This is something I would purchase with my own money. I made a blueberry banana smoothie & it blended everything up very nicely. Would definitely recommend to others!!

[This review was collected as part of a promotion.] Im so obsessed with this thing! The color is visually pleasing and it’s super effective. It efficiently creates perfect smoothies and juices without a ridiculous amount of noise yet it’s powerful and fast. The lid locks in place without a lot of effort and feels secure. I appreciate the versatility of becoming a tumbler and look forward to using this in my morning routine . It’s so well made !

[This review was collected as part of a promotion.] I was incentivized by influenster. First let me start off by saying this tumbler blender is worth every penny. It is sturdy, and the tumbler is not made out of cheap plastic like others. It turned my fruit into a perfect smoothie with in seconds. It is a little loud, but it is quick working. I love that the base suction cups to the counter. It has three different settings, and most smoothie makers do not have thst option. I should know I have owned plenty that do not last. The tumbler is the perfect size for a large smoothie or frozen margarita. I have never owned one that has this much power. All I can say is wow! It is definitely worth the cost.

[This review was collected as part of a promotion.] This Ninja Blendboss Tumbler Blender is so cute. I love the avocado green and light pink colors, since the combo is preppy, a little retro, and very Palm Beach. The size is great for me because it's enough for me to make a big smoothie for myself or to share with my son. The automated settings work great, and I was impressed with how powerful this is and how smoothly it blends. It's easy to clean, and I appreciate that the tumbler, lid and blade are dishwasher safe. The one drawback with this is the lid with the large chug spout. I find this difficult to drink from and pour out of, so I won't be taking this on the go right now. I'm hoping to be able to find a straw or different lid for it.

[This review was collected as part of a promotion.] The convenient design is awesome! The tumbler functions as both the blender and travel cup. Though small in size, its power is not weak. It works well in blending frozen fruits and ice cubes. It’s easy to use with no complicated mechanism and the noise is not overly loud too.   There’s a separate lid with flip cap for the travel cup function. It doesn’t leak and great for on-the-go. The tumbler and lid are dishwasher safe too.

[This review was collected as part of a promotion.] The new staple for my 2 year old for shakes as treats! She is loving them and loves the purple color. I was wondering how loud it would be but it is not loud compared to the ninja foodi smoothie maker, so that is a plus in our books.

[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.

[This review was collected as part of a promotion.] The BlendBOSS is a great personal size blender. Its features are easy to use and perfect for on the go. The design is sleek and easily can be stored away to not take up space or can be left out and doesn’t take up a lot of counter space.

[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
