I got this as an upgrade because my old food processor was so loud and inconsistent.  I've chopped carrots, onions, celery, potatoes (the celery ended up being very stringy) and it was all quick, easy and the cuts were all even.  I grated cheese and that was a bit messy, but clean-up was easy because there are very few grooves on the inside of the cup for food to get stuck in.  Very well thought-out design.
