I bought this last week.  i used it for the first time this evening.  I was slicing potatoes and had to stop and clean it out as all of the potatoes were jammed up inside.  i don't understand why you wouldn't make the blade with a slight  cone shape, flared out at the exit end so that the food falls out more easily via gravity.  i rated this a 3 since i haven't tried out all blades yet, and got it as a bundle with the grinder.  if buying only this item, i would say buyer beware, or plan on tilting the back end of the mixer up to hopefully allow the food to fall out better.
