Two criticisms there but, unfortunately for 1 star less:
I assumed that I get a salt and a pepper mill, as with sets from other manufacturers propagated.
This kit is 2x around the same mill. This can optionally be used for salt or pepper. With the wood grain it is with me impossible to distinguish, in what I now have salt mill and in which pepper. Have therefore the mills themselves labeled, so as not to accidentally grab the wrong spice. A small label 'S' or 'P' at the factory would be chic. But that is probably due to the fact that the mills are not intended to be a set, but should be sold separately.
Furthermore, the cover is a bit loose in the mill. There's too much room between the cover and 'Mühlkörper'. However, it does not affect the functionality. This is only an aesthetic aspect, I want to mention.
