This chopper works well if you only have a small amount of something, but to chop a large onion, for example, it's a little small (you'll need to cut the onion into pieces and do each piece separately). Even though the container holds 3 cups, large amounts of food seem to push their way up the sides out of reach of the blades. The power is good, and it handles hard foods like carrots well. Use caution in handling the blade; I cut myself badly with it in the sink when I was washing dishes right after I got it. Safety If the bowl and lid are not securely and properly locked onto the base, it will not turn on. Ease of Cleaning As mentioned above, use caution in handling the blade.
