(This review was collected as part of a promotion.) This attachment pac is expensive compared to how long the components last.  I used the shredder once and it developed 2 cracks in the housing.  The grinder housing also developed a major crack and I'm not sure if it is safe to use. I contacted Kitchenaid and they told me the parts are only warrantied for a year.  Replacement parts will be $50. No part like that should fail with minimal use.  Disappointed in Kitchenaid's lack of  responsibility for these defective products.
