Nutri Ninja Duo with Auto-iQ Review

The Nutri Ninja Duo with Auto-iQ takes the guesswork out of preparing delicious smoothies and drinks. The blender has created quite a buzz ever since the model was launched a few years back. This is both a blender and a food processor, and a powerful one too. The features you will find here rival top-end models, and yet, the price is affordable. The addition of Auto-iQ Technology makes it even better.

The blender is ergonomically designed and extracts nutrients efficiently. There are five distinct pre-set Auto-IQ programs, three manual settings, and Total Crushing Technology, which gives all options you need to puree, blend, create smoothies, and more. Thanks to the 1,500-watt, 2HP motor, it is 2.5 times more powerful than your average extractor or blender, so you can easily extract hidden nutrients from vegetables and fruits.

The Nutri Ninja Ninja Blender Duo with Auto-iQ is one of the top-selling blenders at Amazon. It is in high demand and has received hundreds of positive reviews. At this time, 520 customers have posted their reviews — 87 percent of them have rated this product 4 or higher on a scale of 5. The blender and food processor currently enjoys an overall rating of 4.5 stars out of a possible 5, which is excellent.

Auto-iQ Technology

Auto-iQ Technology is a useful addition by Ninja to this blender and food processor. All three models of this product come with 5 Auto-iQ Technology programs, which are distinct. Plus, there are 3 manual use programs as well.

What is this Auto-iQ Technology, and what does it do?

This is an automated, one-touch system, depending on what you are making and the container you will be using. The program activates pulses in a unique pattern, blends continuously, and pauses to provide the best result. Because of this smart and automatic process, you don’t have to stop the device to shake or stir. The intelligent technology will make sure everything is combined smoothly.

This is a great help because you don’t have to figure things out yourself. The automated program does everything in the unique “pulse, blending, and pause” pattern. As a result, your food preparations will always be accurate and consistent. This is why Ninja says that the Auto-iQ Technology takes the guesswork out of blending.

All you have to do is simply select a pre-programmed setting. There are five settings to select from. You will get more delicious treats, and the drinks will be healthier also because the nutrients will be extracted from your vegetables and fruits. It even recognizes the container size you have selected.

In the automatic mode, the digital countdown timer calculates the time remaining for the Auto-iQ program you have selected. In the manual mode, the timer will count the seconds for each pulse, blend, and pause, as needed.

Pros and Cons

  • The blades are very good. They break down vegetables, whole fruits, and seeds efficiently. They can crush ice too in seconds for smoothies and drinks.
  • Very good at grinding coffee beans.
  • Vitamins and nutrients can be extracted.
  • Auto-iQ Technology is a great addition.
  • Controls are easy.

  • Pulse setting.
  • Dishwasher safe. Parts can be removed and fitted back easily.
  • Can be stored easily.
  • Stain resistant.
  • Durable. Offers solid, long-term performance.
Things we don’t like:

  • It is fairly loud.
  • Some users have complained about problems when putting on and pulling off the lid.
