Bought the Mahlaufsatz for grinding poppy. Once done, the mill also just fine, not a criticism. Then it goes but to the cleaning. The grinder may not quite into the water, so you build it apart and works with a brush. That sounds good, but is not easy. Pulling out the plastic insert to the grinding ring hurts me, because the plastic on the edge is very sharp. The inner metal insert must be used absolutely accurately. If you have not been paying attention and the metal part has slightly twisted, suddenly everything is too far out and no longer fits together. When that happened to me the first time I was able to get my Baufehler not erklären..Mir shudder every time before disassembly and assembly. This should have been determined can also solve better. You also get the poppy also not entirely out of every corner of the mill. In the long run also not nice.
