I used to buy a lot of ground beef. However, I was told unsavoury parts "may" be added to the ground beef as well as a lot of fat, so I stopped buying. When my son gave me a Kitchenaid Pro 600 Stand Mixer, I got this food grinder attachment so I can make my own. The grinder works well, no problems. Manual says to grind meat that is partially frozen. Follow that advice. If the meat is totally defrosted, some splattering will occur in front of the grinder. My family loves the pasta meat sauce, meatballs, dumplings, etc. I found grinding very lean meat to be a bit dry when cooked, so I added a little fat (when grinding) that I trimmed from roast/steak. Overall, I found the food grinder to be a perfect compliment to my Kitchenaid Stand Mixer.
