We want to have an all-round coffee grinder and can now get both finely ground coffee for espresso and coarse ground coffee for the coffee maker. Cleaning is a bit cumbersome, but to deal with. Through the plastic of the housing turned after a certain time a static one - something mess around included. Indeed there was in the filter of the coffee problem - it gelagte ground coffee in the funnel, where it was not to be, though the coffee was bewust entered correctly in the filter bag. In the cause of research, it turned out we had a very dry heated air that begüntigt static charging of the ground material. Remedy: zunächt we have laid a damp paper towel into the coffee hopper to the coffee beans. Behold, the ground coffee was super in the container, without mess ringsrum and the problem of filter coffee machine was also done. For further operation there was a small block of foam under the cover of the funnel is clamped, which is moistened regularly. As we pour the coffee beans as needed and not in stock, we see no mold problem with the beans. (The miraculous tricks with the aluminum foil in the recovery tank did not work and even led to a blockage of the mill.)
