What bothers me so far is that the ground coffee is not homogeneous, which means that you become a part has very fine ground coffee, which then also adheres to the soil, and on the other hand, the coarser ground coffee. I assume that it is generally in a percussion always comes to this problem and one possibly with a grinder can achieve better results were to the effect.
Furthermore, can the power cable stowed under the mill. Once you do that, however, several times, the cable twisted. So far no failure so, but I can imagine that it is not last forever. But it seems as if one could first just in case installing a new cable because the screwed housing, and does not stick is (another quality Plus).
By and large, a buy recommendation if it is to go fast and the homogeneity of the ground coffee is not a priority.
