I had the plastic one that lasted for a few years, until I started making more and more sausage. I eventually split the plastic case and had to upgrade to a regular grinder. The new one works much faster.

Oh, yes. Don't put the grinding attachment into the freezer before grinding meat. The "Master" (that would be Nepas) says bad things can happen to the plastic case if you do. Don't ask me how I know. Suffice it to say I have a new grinder.
