I researched this and I'm happy with the results.  I've had so-so food choppers that I stopped using, but this one is meeting my expectations and even with my early usage, it's saving me time.  I am happy with this product.  However, I'm a little concerned with the durability of the plastic container.  I will find over time if my fear is warranted, but I'm hoping KitchenAid will have replacement containers if needed.
ALSO: I had to return an incorrect model and found the KitchenAid Help Desk was VERY GOOD, which says a lot to me about commitment to their products.  I was happy to discover that.
