Prone to mold.

Beautiful and powerful, but handle has a little hole that lets water in, that makes it anti hygienic, and prone to mold. I am not sure if I am keeping it just because of that issue. There is no way to clean or dry that part. I am concerned about mold. Ninja should fix the issue, and also create smaller cups for nuts and grinding, like previous model.

It’s exactly what Ive been waiting for!

I am over-joyed with this portable mixer! When we go on road trips I love to be able to mix our breakfast smoothies in hotel rooms to stay on track with our healthy diet. The other mixers are just too small for the amount of frozen berries 1/2 banana, spinach , etc. I include, and had to split to 2 batches. THIS SIZE IS PERFECT, powerful blending & super portable! It’s exactly what Ive been waiting for!

Amazing

This is my first time buying a ninja product and I looked at the price and was like for a smoothie maker no but I can guarantee you that it's 100% worth it I've had cheap smoothie makers that barely did anything and at first when I started with this one I didn't understand how it worked it started it stopped it started again it stopped and then it went in a turbo mode at the end of the cycle the smoothie was perfect I followed the instructions liquid protein frozen fruit and was shocked as I hate raspberries and barely got any of the seeds like other blenders miss it but this one truly amazing if I could give it 10 Stars I would let's go ninja.

Pretty in Pink 😍

I bout this to replace my old personal ninja blender that you push and hold the cup down to blend. This blender is GORGEOUS and I just love the cup and straw it comes with. Not only is it cute but it blends my morning smoothie perfectly every time! I will definitely be adding more cups to the collection. Do not hesitate to buy, especially if you want pink because they sell out freaky fast.

Powerful!!!

[This review was collected as part of a promotion.] This little guy is awesome!!! Super powerful! Its perfect for a single serve beverage or smoothie! Its blends together seamlessly. My only down fall is the ridges in side the cup and on the attachment are a little difficult to clean! Love o can take the cup anywhere on the go! The colors are so cute!

Disappointed

Just used this for the first time yesterday and so far, worked well. Just disappointed in the color as it was different on line. I wanted to leave it out on my counter top to match my other accessories, but the color is really ugly. I would like to give it a higher rating, but am disappointed. My Ninja coffee maker in the light blue was perfect as viewed on line, but this was not.

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.

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 💯😁❤️

Verified Purchase

Best blender I've ever had, very happy.

Grinds seeds up so well, very powerful. It is not noisy considering how powerful it is

Too easy

I have been loving this product. It makes my morning 10x earlier. To be able to blend and just put the lid on go is the best.
