Received my purchase 2 weeks ago and found it to be INCOMPATIBLE with my preowned KITCHENAID MEAT GRINDER.  I suppose it would've made too much sense to list in bold that it was not compatible with all of their meat grinder products?!?!  Now the product is of no use to me and their page tells me I cannot return it.  Very sad day as I own a lot of KitchenAid products and it looks as though I may need to rethink making any future purchases :(  Very disappointed in this company!!
