I love this!  I was previously using a big blender to make smoothies and thought, "why do I need a personal sized one?".  Now I know why!!!!  This is great!  It's so much quicker and easier to clean than a traditional blender.  It also works well to get all types of ingredients chopped and liquified - frozen fruits, nuts, etc.  I add an array of things into my smoothies and it has handled them all very well.  I like that I can just take the cup off, add a lid, and go!  I highly recommend one of these in your life.
