Amazon: Hario Ceramic Coffee Mill

It's a long story why I have two hand grinders. One is a real Hario. The other is a copy. One works, one doesn't. They're both identical except the ceramic grinder. The Hario that's grey works great. The clone that's white can't even grind - it'll only crush. If you get one with the white ceramic, get rid of it.Get price
