I bought this to make smoothies for myself -i.e. small batches.   It works great!    Unfortunately, I bought two other machines, a food processor, and a personal mini blender, first.   Both were disappointing, and I returned them.   The Vita Mix is great.   Little things, like ease of cleanup, and the way the top fits on the vessel, make this machine great.   The E310 is just right for me, and I wholeheartedly recommend it!
