Not enough money for a proper electrical grinder, this mill is very satisfying. Time to grind the quantity of coffee per cup (for me 2 or 3 measurements) is equivalent to the time taken by my kettle 1L. The adjustment must be done step by step, not necessarily obvious to judge at first but gives a lot of opportunities, the screw is large enough for all sizes grinds. Bad: The screw that holds the handle unscrews from time to time, but not necessarily annoying noted, and of course the time to grind. If you have time, it's great, but if you are in a hurry, it is worth taking something else, or else prepare it the night before and close the jar with the supplied plug.
