Query: Terrible!

I have an electric chopper that i use for onions which is far superior to this product. I bought this mainly for recipies that call for diced carrots or potatoes, in order to get nice, uniform pieces. I have tried dicing onions, potatoes, and carrots and each time I had to stand and jump on the lever in order to get it all the way down. Cleaning the grates is also a pain. Definitely not worth the effort!
