It takes a LONG time to grind enough coffee for 4 cups with this. It is not easy to keep stable while you grind. Nice idea to have two glass jars and a silicone bottom for one. Big problem.the screw on top is plastic. After using a few times, the threads stretched out and the top wouldnt stay on. Huge design flaw.
