Read all the specifications and reviews yet no where does it say that you have to have a specific meat grinder! I figured out of course that u need a meat grinder to make it work, but no one said anything about past meat grinders not working! That's right unless you have the very latest meat grinder this thing will not work!!! I bought a brand new grinder in May of 2019 and bought this strainer in July of 2020. apparently my grinder is already outdated and discontinued and wont fit with this thing. the only reason it wont fit is because the cone it just slightly too big to let the ring spin and secure the strainer to the grinder. Why didn't they make the strainer fit the meat grinder instead of a new meat grinder to fit the strainer?? So yeah don't bother buying this unless you have the latest everything, but I'd be careful it might get discontinued too!
