The mill is now about 3 Kg "old". Since I recently Mokka very like, I grind the coffee to "fine dust". That adjustment dial are firmly and then only one notch on loosely. The Mahlergebniss is dust fine indeed. However, I also need a correspondingly long time. For 4 cups in the morning I MAHLE then ever 10 minutes. But that's OK. Workmanship is very good. Was shipped directly from Japan which has already taken some time.
