Works good but have only tried it on fine setting.
Works good but should have an overall cap as seasoning gathers around the inside.

Best S&P grinder set that I have ever used!
Cute chefs cap! Love that they are glass containers with ceramic grinders. Grinds salt granules and pepper corns very finely in both directions. Excellent purchase! Great value!

Great Value!
Color: Tall Set - Black White
Better than anticipated. These are sturdy and work very well. They came with a little funnel to fill, but easy enough without it. They are attractive, I keep on top my stove as I have room. Grind well.
