The Gater manual coffee grinder is hand-operated and easy to assemble and use, as well as small enough to travel with for coffee-lovers on the go. From pour over to espresso, the Gater manual coffee grinder creates a smooth, consistent grind by way of ceramic. It has a lightweight coffee mill with a rubber base for a non-slip grip, comes with 2 jars and a cleaning brush, and facilitates easy grind-setting adjustments by mere shift of the little grinding gear. Definitely a little winner !
