This is a great manual machine, and don't be afraid of taking apart and cleaning it. The gasket (round thing) I had to search on youtube how to remove, it's easy. The only issue I have is that a lot of meat gets stuck in the S bend, you have to remove it with a knife etc to stick up there to get out. Use this for patties. Also, we had to clamp it down firmly to our table by using under bench clamps. Not a problem. It's a beautiful and clean stainless steel machine that works well
