I have had this for about six months, and use it regularly. I do a lot of cooking for my church, and for the elderly. In doing so, I am forever chopping onions, green peppers and I used to use canned chopped tomatoes, rather than fresh, to save time. This chopper makes everything so much easier; takes a couple of minutes to do two onions, four green peppers, and a pile of roma tomatoes. The key is finding a container to place under the chopper, to catch the chopped vegetables. I was able to find a small (just under 7") square Tupperware container, which had diagonal cuts on the corners; it fits perfect. Without this, the chopped vegetables end up everywhere... I am sure you could use a cake pan, and place a towel under the pan so that it would not shift; I find the small bowl works better.Also worth noting, this is not a commercial grade chopper. If you had to do a 50 pound bag of onions every day, you would be well served to get a chopper that costs about $200; something that will hold up under vigorous work. For most people working in their kitchens, this thing is great. I am quite sure it will last my lifetime; it is not cheap, but I am also not pounding through onions 100 times a day.Finally, it is better to cut and obviously peal the onions before chopping them. Placing them with the cut side facing down will make the job much easier. I cut green peppers into quarters, and tomatoes in half; always placing the cut side down, on top of the blades.This thing will save you a lot of time, maybe a few close calls on cut fingers, and you will have uniform pieces of the vegetables you are chopping in no time...
