Hand Crank Coffee Mill BY: Coolife I have used a coffee grinder for many years. Mine was an acrylic one and there was no adjusting the grind. This one is so much better First it is made of glass and silicone. The glass is clear and the silicone is brown like coffee grounds. The grinding unit unscrews and there is a screw-on lid for keeping the coffee you have ground fresh. In other words, you can grind enough for a few days. The grinder is made of ceramic and crushes rather than chops the beans which improves the flavor. It can be set for fine to coarse grind by simply turning the screw. Take off the handle, lift the locking stopper and turn right for fine and left for coarse. Reassemble and you are all set to grind your favorite coffee. Cleaning the grinder is as easy as rinsing with water and letting it air dry. If you are a coffee drinker and want to make the best cup you can, this grinder will help you do that.
