We have always annoyed us that the conventional salt shaker salt not only the egg, but equal to the whole table. That's over with. The spreaders are precisely. Push of a thumb and the salt lands where where you want it. Every now and then obstructed the mechanism, but then helps a quick shake and it goes again. My mills are filled with common salt and coarsely ground pepper already. So I do not know if the force is sufficient to crush sea salt or peppercorns. A disadvantage is that salt and pepper when parking the mills down getting a little out trickle. Each parking so produces a slight edge. My One has appropriately turned from matt stainless steel coasters, in the mills perfectly.
