I love my Kitchenaid mixer and all of the attachments I have purchased for it. The meat grinder and this shredder attachments are the 2 that I use on a regular basis. I have only used the shredder for cheese so far and it works wonderfully. I use it to shred blocks of cheddar and pepper jack and there is little mess to clean up afterwards, just wash everything up with hot soapy water and let dry. That's a lot easier than cleaning up all the mess that I make with the box grater and quicker.
My husband will actually get in the kitchen and help me when I am using or experimenting with all of my attachments, I love that.
