I bought this unit as a "refurbished" model. This was my first food processor. Everything was great for just less than a year. I thought..."OK, it's refurbished. It was cheap. Maybe that's all that I can expect." The main thing I do with this processor is grade or slice cheese. (I have a mixer for bread and a blender for liquids.) The machine gets into a bind and eventually stops and smells like burning metal when I do cheese. After reading other comments about this machine I am reluctant to replace it with another one at regular retail price. So sad. I love all of my other Kitchen Aid products.
