I tried the Ninja BlendBoss, and it might be the best blender to cut through frozen ingredients

Global kitchen appliances brand, Ninja has become well known for its eye-catching designs. Always one to push the boundaries, Ninja debuted the BlendBoss in late 2025 for the US before it launched in the UK in early 2026, and it instantly became the talk of the town due to its unique, Stanley-Cup inspired design.

The latest trend within the world of blenders has been portable designs where you can take your blended creations with you on-the-go – sometimes with the full blender still attached to the cup. The new BlendBoss blender from Ninja is the perfect example of this trend, and combines fun and practicality into one kitchen appliance.

I spent the past few weeks testing the Ninja BlendBoss, and found it to be one of the better blenders on the market for cutting through frozen ingredients – here’s how I got on.

Ninja BlendBoss review: price and availability

The Ninja BlendBoss Tumbler Blender is available to buy for £129.99 / $129.99 at Ninja. It comes in Blue Raspberry, Lavender Lemonade, Watermelon Bubblegum and Cyberspace colours, and has a two year guarantee.

Ninja BlendBoss review: unboxing and set-up

The Ninja BlendBoss comes with the main motor base, the CrushBlade, the BlendBoss Travel Tumbler, a lid and straw. To get started, I removed all the packaging and washed everything before use as it had a slightly ‘new plastic’ smell when I unboxed it.

To use the Ninja BlendBoss, I filled the main tumbler with ingredients before screwing the CrushBlade directly onto the tumbler. I then slotted it onto the motor base which directly plugged into an outlet and pressed one of the control buttons.

Removing the Ninja BlendBoss after blending is the same as fixing it onto the motor base. I’ve tried many personal, portable blenders and have always worried that I’d accidentally unscrew the blade from the main blender and spill my smoothie everywhere – I’m embarrassed to say I’ve done that before! I didn’t experience that with the Ninja BlendBoss as it was easy to unfix and replace the blades with the lid.

Ninja BlendBoss review: design and features

The Ninja BlendBoss has a main circular base that’s powered by a 1100W motor. The base has four control buttons – blend iQ, smoothie iQ, ice crush iQ and pulse that blend your ingredients with targeted pulses, pauses and blend patterns.

The CrushBlade is the six-pointed blade that screws onto the tumbler and attaches to the motor. The blades are incredibly sharp – I nicked myself a couple of times using it – and they easily and expertly cut through ingredients.

On the side of the Travel Tumbler – which is the main blending and drinking vessel of the Ninja BlendBoss – there’s millilitre and ounces measurements. It has a max fill line of 650ml but the tumbler itself measures 710ml. Once you’ve finished blending, you can easily unclip the tumbler and blade from the base and swap it for the leak-proof lid and straw for drinking on-the-go.

In terms of dimensions, the Ninja BlendBoss measures 32cm height, 18.3cm width and 17.1cm diameter, and weighs 2.6kg. When full, the Ninja BlendBoss is still lightweight and easy to carry around, although its handle is quite prominent and can’t be removed so it can take up space in your bag.

Ninja BlendBoss review: performance

I found the Ninja BlendBoss extremely easy to assemble and use. When you switch on the Ninja BlendBoss, the buttons light up automatically and flash at you. If they don’t, that means the blender is not fixed to the base properly, so it makes sure you can’t accidentally use it without everything being screwed on.

The bottom of the Ninja BlendBoss has adhesives so it sticks to your countertop and blends without the entire blender moving around. It makes a good amount of noise when in action, but that’s somewhat to be expected with its high-speed motor and blades.

I mainly used the Ninja BlendBoss to make smoothies as I like to take smoothies with me to the office for my breakfast. I tend to use frozen bananas and berries in my smoothies, and the Ninja BlendBoss blew through these without breaking a sweat.

Typically, I have to blend smoothies with frozen ingredients a few times with other blenders to get everything smooth, but the Ninja BlendBoss easily and expertly sliced through those on the first blend which I was very impressed with. With the smoothie iQ auto program, the Ninja BlendBoss whizzed through everything quickly and pulsed and paused to ensure a full blend.

I’ll be honest, I don’t love the look of the Stanley Cup so the Ninja BlendBoss is quite an unusual design for my tastes. While I do like the handle and found it easy to fit in my backpack, I did find it a bit chunky to travel with, especially for those (like me) who don’t want to walk around holding a cup. The handle is the main culprit here as it really protrudes and can’t be removed.

A major negative I found with the Ninja BlendBoss is that it gets very dirty after use and isn’t that easy to clean-up. After washing the Ninja BlendBoss in my dishwasher, there was still smoothie residue in the crevices of the blender and blades, and there was even muck in the handle that I haven’t been able to get out.

Ninja BlendBoss review: verdict

I’ve been pleasantly surprised by the Ninja BlendBoss during my testing. While the design is not really my thing, and the clean-up leaves a lot to be desired, the Ninja BlendBoss is easily the best blender I’ve used for cutting through frozen ingredients.

The Ninja BlendBoss is my go-to choice for making smoothies, and it’s extremely good at cutting through ice. Its controls are easy to use, and the whole removal process is simple – it’s highly unlikely you’ll spill your blends when removing the Ninja BlendBoss from its base.

Will the design be for everyone? No, but if you love travelling with drinks, the Ninja BlendBoss could be a great blender choice for you.

Ninja BlendBoss review: alternatives to consider

If you fancy an alternative that’s slightly smaller and more travel-friendly, the Ninja Blast is what I’d recommend. It’s more compact than the Ninja BlendBoss, and has one-touch colour-coded controls for quick blends. You will have to travel with the motor and blades attached, though, but this can help prolong the freshness of your smoothies.

The Nutribullet Flip is another good portable, personal blender. Compared to the Ninja BlendBoss, it’s cheaper at £99.99 / $99.99, and it has more of a water bottle design. It can require a few extra blending cycles but it’s great at blending ice and is fully insulated so it keeps things as cold as possible.
