So far, I am very happy with my unit. I had delayed purchasing because I wasn't sure if 7 cup was big enough but actually it is the perfect size for me!  It sits nicely on my counter top and is quick and easily for throwing in foods for chopping- adding to soups, sauces etc. Also to whip up some cream, make pancakes, dressing anything!  It has a hefty motor too, I even dough in it yesterday for making pasta. 
The pieces assemble easily and it can all go in the dishwasher.. The only thing I have done yet is figure out slicing but I'll get there ;)
