I've had the grinder for over fifty years and love it. Originally I used it with a Kitchenaid 4C model, which was less powerful than the Classic model you have, and it worked just fine. When my trusty 4C model turned 49, I donated it to our local kitchen tool library, where it is still in use, so it's clear that using the grinder didn't strain the motor. I upgraded to an Artisan model because I wanted to be able to knead bread, which was beyond the 4C's capability. I'm still using the grinder. I also have the sausage stuffer which works well, but I don't use it very often, because I'm happy with making bulk sausage that I can form into patties or crumble as needed.
