The Ninja TWISTi 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 Nutri DUO or the Ninja Foodi Power Βlender & Processor System. There's also a 24-ounce jar for single-serve smoothies. Unlike other full-size Ninja blenders, it has only one speed setting.
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. It's unsafe to use for hot blending and has only one speed setting, which you may find isn't ideal for some recipes.
The Ninja TWISTi is excellent 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.
The Ninja TWISTi is very 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're regularly serving 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.
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 a bit longer than some of the best ice-crushing blenders; ice can melt during the blending process.
The Ninja TWISTi isn't safe for hot blending, so if you want to make soup, you need to 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.
The Ninja TWISTi is adequate 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.
The Ninja TWISTi is a compact blender. Even though it's a full-size blender, its size and capacity are closer to some personal blenders. It's only a bit heavier and a few inches taller than the Ninja Foodi Power Nutri DUO.
The Ninja TWISTi has a good build quality. The jars and lids are thick plastic, and the gears and transmission are rubber. The flap on the lid is easy to maneuver, and the suction cup feet under the motor base also do a pretty good job of keeping it in place when you're blending. That said, the materials used don't feel sturdy or premium, and the motor base feels cheap, especially the buttons.
The main jar's capacity is 34 ounces, less than most full-size blenders, like the Vitamix Explorian E310 (48oz) or most other full-size models from Ninja (72oz). The additional jar holds 18 ounces and is a good size for single serves.
Both jars are made of plastic and have measuring marks. The jars, as well as the lids and blades, are top-rack dishwasher-safe.
There's one blade assembly that works for both jars. It has eight thick, very sharp blades and can go on the top rack of your dishwasher.
The lid for the main jar has a knob on top that rotates the built-in tamper or arms inside the jar. The knob can only turn counter-clockwise. There's also a to-go lid included for the personal jar.
The Ninja TWISTi High-Speed Blender Duo has a power cord long enough to reach a nearby outlet. There's no stowaway compartment or place to wrap the cable when it's not in use.
The Ninja TWISTi is fantastic for small batches of fibrous ingredients. It makes a very silky purée with ingredients like kale. It's a small step down from the Ninja Foodi Power Nutri DUO (which gets a perfect score) since it's a bit slower and leaves behind a few specks, but most people should be very happy with its processing ability.
The Ninja TWISTi does a fantastic job of processing fibrous ingredients in its main jar. Filled to its full capacity, it makes a very silky puree with ingredients like kale. The process is a bit more hands-on than with the 24-ounce jar, because you need to turn the knob to operate the built-in tamper. If you don't, some ingredients can get caught between the arms and the sides of the jar.
The Ninja TWISTi is excellent for ice crushing. Using the high-speed switch to simulate a pulse mode, it takes about two minutes to make snow-like ice. Because it takes a little longer than some blenders, the ice tends to melt a bit during the process. However, this is if you work with six ice cubes at once. We usually test a batch of 12 ice cubes in a full-size blender, but this blender's main jar is small. You end up with a lot of unprocessed chunks if you use that much ice at once. If ice crushing is a top priority, most other full-size blenders, like the Ninja Foodi Power Βlender & Processor System, are better for ice crushing.
The Ninja TWISTi is well-suited for making nut butter in its main jar. It doesn't take very long to produce smooth, spreadable nut butter. There may be a bit of unprocessed dust caught under the blades. You need to use the knob to turn the built-in tamper, so it's not a totally hands-off process.
This blender has one speed setting. It's fast, which can be annoying if you want to start at a lower speed to avoid ingredients splattering up the sides of the jar or over-mixing something like salsa.
The Ninja TWISTi has a few 'auto-iQ' blending programs, which means that the program alternates between blending and pulsing. It also stops automatically, so you don't need to keep an eye on it. However, the blender doesn't detect how much food is in the jar or which jar you're using, and you may need to run a program more than once or use the manual blending mode to get the results you want. There's a dedicated button for pulse mode. You can also press 'start/stop' for manual mode, which runs the blender continuously for 60 seconds.
The Ninja TWISTi is a bit tedious to clean. The built-in tamper requires scrubbing, and some parts of the lid are hard to reach with a brush. The blade assembly gasket also tends to trap residue and needs extra attention with a sponge or brush. As with most Ninja blenders, the blades themselves are very sharp, so you need to be careful not to cut yourself.
The Ninja TWISTi comes in either 'Platinum' or 'Gray'. We tested the 'Gray' color, and you can see the label for the unit we tested here. If you come across another variant, please let us know in the discussions, and we'll update the review.
The Ninja TWISTi is a compact full-size blender, like the Vitamix ONE or the Nutribullet Rx. The main jar has a small capacity, but its '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 only one speed setting, which is a bit disappointing for a full-size blender.
The Ninja Foodi Power Pitcher System and the Ninja TWISTi perform similarly. The Pitcher System is a bulkier blender, but its main jar has a much bigger 72-ounce capacity. It makes it more suitable for ice crushing and for preparing larger servings. It also offers a few different speed settings, and it's easier to clean by hand. You may prefer the TWISTi if you don't mind its smaller 34-ounce capacity since its more compact design takes up less space on your counter.
The Vitamix Explorian E310 is better for most purposes than the Ninja TWISTi. 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.
The Ninja TWISTi is better than the NutriBullet Rx for most purposes. The TWISTi does a better job of processing fibrous ingredients for recipes like green smoothies and comes with a resealable to-go lid for its personal jar. It's also better for tough tasks like making nut butter. However, you can use the Rx to heat ingredients as they blend, so you may prefer it if you want to use your blender to make a quick batch of hot soup. The Rx is also easier to clean by hand.
The Ninja TWISTi 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 has a significantly better build quality. However, it has only one speed setting. The Vitamix ONE has a variable speed dial that gives you more control over the blending process.
