I can only give as a barista aficionado my own comments on the mill Graef CM 702. It works well, the resulting ground espresso succeed with my Gaggia Classic very good (freeness 10). Only drawback is probably the fact that the light ends of the material to be ground flying through the counter and spread so that the workspace. But I think for the price this mill is unbeatable. It pays to try them and to take a maid in purchasing. Must the Barista anyway.
