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

Smoothie maker on the go

Ended up purchasing this smoothie blendboss which's been such a game changer. It sits on my counter top without occupying much space and is such a lifesaver every morning for my protein smoothies. Cleaning it is also a breeze as i just throw it in the dishwasher. The blender is also very powerful as it crushes the ice in my smoothie pretty well.

Great blender!

I've been using this blender for about a month now and I'm very happy with it. It's big enough for my morning smoothies, strong and powerful enough to blend fruit, ice, etc. The process is easy and fast; and cleaning is much easier than my previous blender. I'm definitely happy that I made this purchase.

Ninja BlendBOSS Review

I am thoroughly impressed with the performance of the Ninja BlendBOSS™ Personal Blender. It handles frozen fruit, ice, and leafy greens effortlessly, creating perfectly smooth textures every time. The motor is incredibly efficient, making quick work of my daily morning smoothies without leaving any unblended chunks behind. Clean-up is also a breeze, as the cups and blade assembly rinse clean in seconds. However, there are two minor drawbacks worth noting. First, the motor is very loud during operation. While it blends quickly, the noise level is quite intense for a personal blender. Second, the push-to-open flip top on the travel lid feels a bit flimsy. The plastic mechanism seems fragile and like it could break over time if handled roughly. Despite these two issues, the sheer blending power and convenience make it an excellent investment. If you need a fast, heavy-duty personal blender and do not mind a bit of noise, this machine is a fantastic choice.

So pretty

I wasn't expecting this to be so beautiful! As soon as I got it I opened it, washed it and used it! No problems with the product so far! My one issue was how it was shipped. I'll attach a photo. But I wish it was in another box rather than the whole world seeing what it is. People steal packages so I feel how it was shipped didn't help. Also I wish they made more pretty colors like this and more pink!

Good Product

Very good and the IQ blend is very helpful. The only thing I don't like is when you put the lid on and want to use the straw the open side of the lid just sticks out. The design should have allowed for the lid to drop all the way down. Otherwise love the function and everything else!

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.
