I used the coarsest setting for my cold brew and it turned out perfect.

When I grind even at the more coarse setting, there are still fine particles that like to clog up the filters that I use.

I also think every setting is too fine.

When removing the lid, the fine coffee chaff will always fly off into the table or onto the floor!. Secondly, the majority of the grind settings is decent, but even on the coarse setting, there is still a good amount of ultra fine powder like grinds, for coffee purists and pour overs, this ultra fine grinds defeat the purpose of a burr mill grinder - might as well go with a blade style grinder where you will end up with some ultra fine grinds.

At the highest setting, my coffee grinds looks the same as my lowest setting - and that's a real problem when you doing a pour over, the filter constantly gets clogged because the grind is too fine
