Negative Product Points
no instructions, turning the adjusting knob is difficult.
Detailed Commentary
Granny's suggestion on cleaning; occasionally grind some (unboiled) white rice to remove oily coffee deposits in the mechanism. Throw away the first coffee grind as it is likely to contain a little rice powder.
Use a wrench to adjust the knob for a finer ground. If you do it by hand, your grinder won't produce a sufficiently fine ground. The coffee doesn't look as finely ground as with a "professional" grinder, but don't let this deter you. If you tamper it well, it has the same consistency and produces a very good espresso.
Not every Zassenhaus manual mill can grind finely enough for espresso machines; this particular grinder is marked "espresso".
Buying Experience
I got it in a small coffee shop in Amsterdam, Geels en Co.. Nice old family-owned shop close to Central Station in the Warmoesstraat. Friendly staff, good selection of products. A little further down the street, you'll find Wijs en Zn., also a very nice shop for coffee geeks and a supplyer of the Royal Court.
