I got this a while back and I know a lot of you are like me and still have not pulled the trigger on a real meat grinder. I have used these quite alot and they improve grinding performance one heck of a lot. Plus the two discs that come with the food grinder will still work and that gives you a full set of sizes. The stuffer plate is a little better than what comes with the unit but it is still quite a chore to stuff with. I just thought I would kick this out there. Big improvement and easily found on amazon. The set is a little pricey at 30 bucks. I love my KA meat mangler again!
