Query: a heavy piece of metal

This grinder is built like a tank. When you take it apart, the metal gears are solid stainless steel pieces. The machine looks nice on the counter with its chrome finish.However, the constant left-over powders are annoying. There has got to be a better design to prevent this. Also, I found the grind particles are not at all even, no matter how I adjust.A nice looking machine but fall short on performance.
