Allow me to start with the dicer disc and blade, of which it works very well for celery, onions, green peppers and carrots (what I tried). The shredder for me didn't work well at all. I tried shredding cabbage for coleslaw, it worked terrible, came out slow and like mush, I gave up and used a hand shredder. Tried shredding carrots and onions for coleslaw, this too was not a good experience, like one would expect these products to shred. So far this is the only items I have tried, due to the newness of receiving Food Processor. I hope Kitchenaid will improve on making this better or contact me if I am doing something wrong. I would not recommend this product at this time, until these various things I mentioned, improve in quality.
