I've been a proud Ninja blender owner for many years. I enjoy the powerful blending at a reasonable price. The Ninja® Professional Plus Blender DUO® with Auto-iQ® is a wonderful upgrade. It's got a slimmer profile, so it stores easier. The large carafe can hold smoothies for the whole family. I was able to make a crushed fruit and ice drink quickly, thanks to the powerful motor. The tall blade system ensures that everything is blended together smoothly. I don't encounter chunks being missed. The addition of two single serve blending cups has made it easier for drinks on the go. I can blend a personal smoothie or frappe, screw on a lot, and be ready to go in no time. I look forward to many more years of being a happy Ninja blender owner.
