Quality German Craftsmanship; no plastic parts.  Consistent fluffy grinds; no powder/chunk issues.  Wood exterior is well finished.  Good looking product ... nostalgic.

Hand grinding for more than one serving can be onerous.  Not for people with weak muscles in arms (seriously).  Calibration knob likes to move off last set calibration too easily.  Grounds can be difficult to remove from bottom wooden drawer.

I have owned the Zassenhaus hand coffee mill for going on 3 years now.  For about 2 1/2 of those 3 years it was the only grinder I had.  It has always provided a very high quality grind, consistent in that it would never do the powder/chunks issue that many grinders often fall prey too.  The downfall of the grinder is that it is manual and does take some effort to produce a grind.  Over one serving (2 1/2 tablespoons of unground beans put into the grinder), and you will get a good workout (read sore arms for many).  I consider myself to be in excellent physical shape, strength-wise and cardiovascular-wise, and it would definitely increase my heart rate/respiratory rate.

HORRIBLE.  I called Zaccardis (located in New York) and asked if they had the premium model ($129+).  They informed me that they had.  Since Zassenhaus is / was in short supply at the time, and I wanted it bad, I decided to take a drive down to their store in New York (from upper Connecticut where I am from ... a 3 hour drive one way).  When I got there they did not have it ... actually had not had it for quite some time, CONTRARY to their web site and personal phone call I made to them.  Their store was in shambles ... I guess that they were moving???  In any rate, I ended up with a store demo of a lower-end model.  I used it for a bit, worked OK ... after which I ordered a bunch of them directly from a Zassenhaus-authorized distributor, kept a similar model, and sold the rest.

Bottom line:  Buy direct from Zassenhaus if possible, to avoid dealing with the issues I had to confront.
