The Porlex Mini Coffee Grinder has ceramic burrs and a stainless-steel housing, which not only makes it easy to clean, but more resilient than glass burrs, and produces less static than plastic burrs. The conical ceramic burrs don't rust, are easy to clean and stay sharper for much longer than steel burrs. The thing that sets this apart from other hand grinders is the speed and ease of grind. This is down to a couple of features: a long steel handle that connects solidly to the grinder and the ability to hold the grinder steadily in one hand while turning the handle with the other.
