For three years I have seen a very similar hand mill from Kyocera with the same ceramic grinder and plastic housing in use and use them for Turkish coffee and mocha in Schraubkanne. Since I am very happy with it, I now have to appoint the Porlex Mini and use it "misused" as a spice mill. Works great, served very fine and with much less effort than the usual spice mills with smaller grinder. The advantage of the stainless steel case is that it is not static charges during the grinding and the grinding material therefore does not stick in the lower container.
The only point of criticism the ground material does not seem to be as homogeneous as good electric mills. Seriously, it is quiet, takes up almost no space and also served smallest quantities without somewhere in the mill remains a rest.
