Ninja Master Prep QB900B Blender Review

A powerful tool for any modern kitchen, the Ninja Master Prep QB900B provides a unique mixing system that can uniformly blend almost any type of ingredient. Many users favor the Ninja Master over other types of blenders, because the device is especially good at creating frozen beverages and smoothies, as well as performing all the other tasks you would expect a blender to be able to handle. This kitchen appliance is very powerful without becoming difficult to control, giving you all the power of a full-sized, 400-watt blender in the palm of your hand. The device is capable of crushing ice into snow in seconds, blending frozen fruit into creamy smoothies, and chopping fresh ingredients evenly.

The device is capable of mincing, dicing, chopping, blending and pureeing almost any ingredient that you place inside the 16-ounce chopper bowl. The Ninja Master also comes with a 48-ounce chopper bowl that’s designed for frozen blending, and achieving a consistent blend when frozen ingredients are used.
