I’ve loved using my kitchenaid mixer for a few years, and I decided to purchase the sausage kit.  Grinding the meat seemed a little tedious, but the machine got the job done.  Stuffing the casings is where the issue came in.  As with other reviews, my main complaints are excessive air in the stuffer, and needing a second set of hands to manage the sausage as it grows from the end of the attachment.  There seem to be two main design flaws:  The hopper isnt’t big enough, and the plunger is not appropriately sized to push the meat mixture through smoothly.    This accessory can eventually get the job done, but Not without a lot of frustration.  if you want it done efficiently and easily, you should consider a purpose-built sausage stuffing device.
