We bought to replace a plastic manual grinder, and what a great accessory for our 20-year old Classic Kitchen Aid mixer. Right out of the box, cleaned as recommended and ground a couple of pounds of beef. So fast and evenly cut, easy to clean. Would highly recommend and hope to make sausages at sometime. Am looking forward to grinding pork  for dumplings. We also have the Kitchen Aid pasta roller set and food shredder set, all are wonderful to own and use regularly.Only Con are the parts that are not dishwasher safe, but that is small compared to the quality of these products.
