I have a burr grinder, so as the beans grind, they fall down to the container. I just press a button to grind and another to shut it off. The coarseness of the grind depends on how I have it set. Since I use an electric drip, I have it set somewhere in the middle of the range.
You want a medium grind for electric drip pots. Fine for espresso, coarse for a french press.
