This is likely a private label manual burr grinder. However I find it produces a very consistent grind from very fine to medium. Once you get more coarse than medium, the burr wobble begins to produce an increasingly variable grind quality the more coarse you get. This works well for espresso and pour over and passes for french press grinds although the french press grind is a bit more variable in consistency. As with other ceramic burr grinders, they don’t last forever. But while they are sharp, they can produce a very nice consistent grind and this one is a great size for travel or camping.
