The blender and food processor parts are great, but the smoothie cup design is very flawed.  It is made in two parts and where they are put together, ingredients permanently get stuck.  I've soaked it, tried toothpicks and fingernails, but nothing can get in there to clean it out. It  looks disgusting and is very unsanitary.  I cannot use it anymore.  Now I have to use the the big blender to make my daily protein shakes.  Bummer.
