Customers Say
Powerful, compact Ninja Blend Boss excels at smoothies, ice crushing, and on-the-go use with leakproof tumblers. Easy to clean and stylish, but notably noisy and could use more recipe ideas and extra tumblers.

Great smoothies but very very noisy no recipes
Makes great smoothies, but very very noisy, could do with a long brush for cleaning. Some recipes ideas

Absolutely amazing
[This review was collected as part of a promotion.] I love the colour and of course the machine is powerful. I love the tumbler as well

Game changing
The Ninja Blend Boss feels less like a blender and more like controlled chaos in the best possible way. It powers through frozen fruit, ice, and tough ingredients with an almost ridiculous confidence, leaving behind flawlessly smooth textures that taste like they came from a high-end café. It’s fast, brutally efficient, and refuses to be slowed down by anything you throw at it. What’s impressive is the balance — raw power without sacrificing consistency or usability. Even thick blends come out uniform, silky, and ready to pour. In short, it doesn’t just blend; it dominates the kitchen counter.

Compact and powerful + love the tumbler cup!
I love this powerful, yet compact blender! It blends frozen fruit into perfectly smooth, super thick smoothies. No chunks and no scraping down the sides. And it takes up very little space on the countertop. Plus, I love the tumbler cup - cute, yet functional - I can make a smoothie in the morning, take it with me on my commute, wash it out at the office, and use it as a water cup. The lid is leakproof too so I don't have to worry about any spills in my bag. Love love love this blender

The best blender
I absolutely love this blender. Since having it, I have made a smoothie every day! It blends frozen items brilliantly and mixes in powders, nuts and seeds too.

Another great gadget
This is my third Ninja, already having an iQ10 and Soupmaker. This BlendBoss is great: compact but powerful and the pink colour is so cute and fits into my blue and pink kitchen aesthetic perfectly.
Ceecee, 45 - 54, Glasgow
Stylish and high quality product!
Brilliant gadget! I’ve used this almost everyday since it arrived. It’s fantastic for making smoothies and milkshakes. It’s simple and quick to use. A few reviews suggested it was noisy, which is true, but feels acceptable for a blender. I love the sleek and stylish design as well. Overall, I’m delighted I purchased this and would highly recommend.
A happy customer, 35 - 44, South West
Fab blender and looks great too.
Over the moon with this smart blender. Since receiving it I have made numerous smoothies and iced coffees, can’t wait to try some cocktails. It’s so easy to use and more importantly easy to clean. The tumbler is a good size with a leakproof lid and handy straw. I did buy an extra tumbler as I didn’t want to share my smoothie ! Would totally recommend.

The Ninja BlendBoss is designed for smoothies and frozen drinks, not slushes. For authentic slush texture, the Ninja SLUSHi range like the FS300UK or FS600UK is the better choice, as they’re built specifically for that purpose.
The BlendBoss works wonderfully for dips and spreads. Begin with liquids to help the blades blend smoothly and deliver a creamy finish.
