This is a great attachment for the Bosch Universal. I purchased this unit a couple of months ago and didn't have an opportunity to use it until last week. I decided it was cold enough to make chili. So, I pulled a couple of pounds of venison stew meat that I had put away and 5 pieces of bacon slightly frozen to grind. It took longer to pull it out of the box and set it up than it did to grind the meat. It worked perfectly and I didn't notice any gristly parts in the meat. It was excellent ground venison and the chili was great. My wife still talks about how good it was. I would highly recommend this for your Bosch machine. It does a fantastic job of grinding up the meat and the clean-up is easy as well.
