Excellent grind, more work. For those willing to be slightly impractical in search a better shot.
Positive Product Points
Very even, low-temperature grinding; relatively quiet; good tactility; very good build quality; intuitive to use; continuous grind adjustment from boulders to dust. Easily the best manual grinder I've ever used.
Negative Product Points
More physical effort (if you're feeling lazy); awkward to hold; can't grind more than 20g of coffee at a time (not a problem for just-in-time espresso, but would be annoying for grinding eight measures for the vacuum pot); no markings on adjustment wheel (a problem for those using it for various particle sizes.) Pretty expensive, too; about A$100 (~US$65)
I'm unsure that this Zassenhaus Manual Mill is the one generally discussed in North American sources. The biggest drawback of my mill is that it's _not_ fixed to the benchtop, so you have to grasp it firmly with one hand and crank with the other. As the mill is a slightly curved wooden box, this is not the most ergonomically satisfactory solution.
Still, it produces an appreciably better grind than my Braun KMM-30, in about the same amount of time. And those conical burrs _are_ a thing of beauty.
(Oh, and very importantly--it's quiet enough not to wake the baby.)
