Excerpt: Bought this grinder in 2006 for my daughter. She took it to college with her. We use it because it doesn't make a mess. Until a couple of days ago it was running great and then it just stopped. I'm back to buy another one. We cold brew in the Summer so we use it a lot. The grind is perfect. You make your own course or fine grind and it is perfectly fine for espresso just don't fill the container to capacity for a very fine grind.
