Our Verdict
Ninja Blender Duo with Auto-iQ BL642
Ninja Professional Plus Blender DUO with Auto-iQ
The Ninja Blender Duo with Auto-iQ BL642 and the Ninja Professional Plus Blender DUO with Auto-iQ are similar blenders. The BL642 comes with a 72-ounce pitcher and three personal jars for single-serve smoothies, and the DUO comes with the same 72-ounce pitcher and only one personal jar. The DUO is quieter and makes a smoother blend with big batches of fibrous ingredients. Otherwise, they perform about the same.
