5 Star for it's function when it works.  1 star for durability and inability to purchase replacement parts.
Loved this roller.  Made making homemade ravioli a dream.  Used it about 5 times.  Went to use it last night and the rollers wouldn't move.  Worked perfectly the last time we used it.  After inspection the stud that drives the rollers had sheared cleanly off. I expect more from the Kitchenaid Brand, especially for the price of the item.  Is there a way to replace just this part?
