I used a manual coffee grinder for a few months, but this Sunbeam electric grinder does in 10 seconds what it took me 2 minutes to do with a manual grinder! It works great. My only caveat is that the small on/off button is designed to be used with an espresso style handle but I grind the coffee directly into an AeroPress chamber. It works but there's only just enough vertical clearance to fit the AeroPress chamber under the spout.
