1. The mill can be handled poorly: trying to turn it off on a table and to cranks, will remain certainly not there. Adherence is and press very strongly is called for, so that they will not tip over or slip away. That would be in itself a problem, but:
2. For a milling operation á 15g coffee beans one must ever 10-15 minutes grinding. 400-800 revolutions are there already inside, used depending on the coffee bean you. A monstrous force / time with this mill.
3. Will you must be Re-balancing every time clean the mill. Up to its previous freeness caught, pass well again experiment 1 hour because there is no scale or the like for the grinder.
4. Coarse ground material is completely homogeneous. The finer you grind, the more homogeneous, however. However, the finer you grind, the grinding time increases exponentially (caution!)
5. Any old coffee mill grinds better than this one. In principle, 35 with the benefits of a glass vessel where I can keep coffee.
The good reviews here on Amazon at this mill make me really suspicious. Dear read the reviews!
