The function of this device does not contain what the design or price verpricht. The grinding results are poor. The gradation from coarse to fine should be possible by means of a rotating screw that manual specifies this precaution is not accurate. Also on the screw itself finds no indication in which direction it should go. Grind After five servings it was then. Even if you completely tightens the Mahlwwerk and then opens only half a turn, so ultra-fine, the plant served only very roughly like candy, which only slightly improved when the ground material by man hunts again. The fact that you can pull the plug again after each grinding process, even if they had previously suffered almost complete, indicates a lack of structure. This goes for the rest of the loose fit of the plastic cover, which you can pull though, but so much play in the guides that goes along this constantly during milling.
