Query: Not Worth the $$

I bought this because I was cooking a huge amount of chili for a charity event and needed to chop several onions. For that one event it was perfect - I chopped several onions and tomatoes in a fraction of the time it would have taken by hand. However, in the long run, this gadget proved to be difficult to keep clean, especially when you're chopping onions. The top of the device is easy to clean with the little cleaner that you get (or a fork), but the actual blades are trickier. The fine skin of the onion can get stuck to the blades and it takes some real effort to get them clean. Also, the commercials for this are a little deceptive, as it takes some real muscle to push the top down to chop the veggies - you'll need to quarter them at least before adding them to the chopper. For $20, I expected something a little easier to use and maintain.
