Review on Ninja SS151 TWISTi Blender DUO - 1600 WP Smoothie Maker & Nutrient Extractor, 5 Functions + SmartTORQUE, 34-Oz. Pitcher & (2) To-Go Cups, Gray by Jared Poinson

1600 rpm motor blasts through everything that I have thrown at it. It emulsifies without the dangers of a device like the Nutribullet. I loved all of my bullets and the fact that In went through 3 of them in 6 years is proof enough that they work and they wear out easily. I can not speak to the durability of this produce yet, but I do have another Ninja product over 1 1/2 years old and is still as great as the day I bought it. This thing is bad ass!
