The Ninja TWISTi High-Speed Blender DUO is a compact full-size blender. Its 34-ounce main jar has a built-in tamper that you can use to stir your recipe, similar to the 'Smoothie Bowl Maker' jars that come with other Ninja blenders like the Ninja Foodi Power Blender Ultimate System. There's also a 24-ounce jar for single-serve smoothies. Unlike other full-size Ninja blenders, it has only one speed setting.
Our Verdict
The Ninja TWISTi is decent for multi-purpose use. It's well-suited for making a smooth puree with fibrous ingredients. It also produces smooth, spreadable nut butter and snow-like crushed ice. However, its main jar has a small capacity for a full-size blender. Some recipes, including thick mixes like nut butter, require you to use the built-in tamper, which makes it a bit less convenient than some blenders. You also can't use it for hot blending.
- Easily processes fibrous ingredients.
- Built-in tamper feature helps with thick mixtures.
- Good build quality.
- Small capacity.
- Loud.
The Ninja TWISTi is great for single-serve smoothies. Using the 24-ounce personal jar, making a silky smoothie with fibrous ingredients like kale doesn't take long. There's also a resealable lid for the jar, which is nice if you like to take your smoothie with you on the go. The jars, lids, and blades are also dishwasher-safe.
- Easily processes fibrous ingredients.
- Personal jar and to-go lid included.
- Good build quality.
- Loud.
The Ninja TWISTi is good for multiple servings of smoothies. If you fill the main jar to its full capacity, it can produce a silky blend with fibrous ingredients. That said, the main jar's capacity is small for a full-size blender, which isn't ideal if you regularly serve a crowd. Ingredients can sometimes get stuck between the tamper arms and the walls of the jar, resulting in unprocessed pieces in your smoothie. Rotating the tamper helps avoid this. The main jar is difficult to clean by hand, especially the lid.
- Easily processes fibrous ingredients.
- Good build quality.
- Loud.
The Ninja TWISTi has a small main jar and does best when crushing about six ice cubes. It's limiting if you're looking to process a lot of ice, but it's still suitable for making ice for single-serve frozen drinks or cocktails. It takes longer than some of the best ice-crushing blenders; ice can melt during the blending process.
- Good build quality.
- Can't crush a lot of ice at once.
- Loud.
The Ninja TWISTi isn't safe for hot blending, so if you want to make soup, you must let your ingredients cool down first. The main jar has a small capacity, so depending on your recipe, you may need to work with multiple batches. However, it makes a very smooth puree with fibrous vegetables like kale or broccoli.
- Easily processes fibrous ingredients.
- Good build quality.
- Small capacity.
- Can't hot blend.
- Loud.
The Ninja TWISTi is okay for professional use. It's well-suited for processing fibrous ingredients for smoothies, and the built-in tamper is handy for making smooth nut butter. It can produce small batches of snow-like crushed ice as well. However, you can't use it for hot blending, and it has only one speed setting. While it's well-built overall, the motor base feels a bit cheap.

Updated Oct 21, 2024:
We've updated the results to more accurately reflect the blender's performance. The score for Fibrous Ingredients (Small Batches) processing changed from 9.5 to 8.5 because of the blending time. The score for Fibrous Ingredients (Full Capacity) changed from 7.5 to 6.0 because of the blending time and the need to use the built-in tamper.
- Updated Mar 22, 2024: We've made minor edits to the text to bring it up to date.
- Updated Feb 14, 2024: Added a note to noise that the Brentwood 12-Speed Pulse Blender with Glass Jar's is quieter.

Differences Between Sizes And Variants
The Ninja TWISTi High-Speed Blender DUO (SS150) comes in either 'Platinum' or 'Gray.' We tested the 'Gray' color; you can see the label for the unit we tested here. There's also a variant with the model number CO150B available from Costco (U.S.). That model comes with two 24oz personal jars ('Nutrient Extraction Cups') instead of just one, but we expect our results to be valid for it as well.
If you encounter another variant, please let us know in the forums, and we'll update the review.
Popular Blender Comparisons
The Ninja TWISTi is a compact full-size blender, like the Vitamix ONE or the Nutribullet Rx. The main jar's 'built-in tamper' is useful when working with thicker mixes like nut butter. This blender is also very well-suited for single-serve smoothies since, unlike the Vitamix ONE, it comes with a 24-ounce personal jar and a matching to-go lid. However, it's not very versatile since it can't process hot ingredients and has a small capacity for a full-size blender.
If you're looking for other options, check out our lists of the best blenders for smoothies, the best Ninja blenders, and the best personal blenders.
The Ninja Foodi Power Nutri DUO and the Ninja TWISTi High-Speed Blender DUO are quite similar, so which you'll prefer really depends on how much capacity you need. Both blenders come with jars that have rotating arms inside, which helps process recipes like nut butter without any need to remove the lid and stir. The Ninja TWISTi is a full-size blender with a 34oz capacity in its main jar and an 18oz 'Smoothie Bowl Maker'. The Foodi is a personal blender, so it has a smaller 24oz capacity in its biggest jar and a 14oz 'Smoothie Bowl Maker'. The Foodi has a slightly better performance for most recipes, including smoothies, so it's a better option if you don't mind its smaller capacity.
The nutribullet Rx is better than the Ninja TWISTi High-Speed Blender DUO. The Rx makes a smoother blend with fibrous ingredients. You can use it to heat up ingredients for recipes like soup and it's easier to clean by hand as well as quieter. The TWISTi is a better ice crusher and comes with a travel lid for one of its jars.
The Ninja TWISTi High-Speed Blender DUO is better than the Vitamix ONE. Both are compact full-size blenders, but the Ninja comes with a personal jar and a to-go lid for smoothies. It's also more versatile since it can make smooth nut butter and snow-like crushed ice. It also has a significantly better build quality. However, it has only one speed setting while the Vitamix has a variable speed dial that gives you more control over the blending process.
The Vitamix Explorian E310 is better for most purposes than the Ninja TWISTi High-Speed Blender DUO. It has a better build quality, a larger capacity, and a better performance when processing fibrous ingredients, nut butter, and ice. It can process hot ingredients. On the other hand, the TWISTi comes with a personal jar with a to-go lid for smoothies.
