I have the mill last Christmas gifted by my children for Christmas and the mill has since several times a day in use. I can not understand how from insufficient freeness, Sauerein etc. in some Rezesionen with the ground coffee the speech is. The mill I use for espressos with different beans. The machine was set correctly at the factory. Espressos with level 5 or 6 on the adjustment ring are always good, the ground material is fine and good to tampern. I've noticed that a good result depends on a lot of the beans used. At first I had the problem that I first even thought the machine grinds poorly and / or my Lelit Espresso Machines makes a bad espresso. Once I'm on more expensive beans (no longer in kilos supermarket pack, but by smaller fresh Rösterein) switched. Everything works fine and the espressos are perfect. So it does not always have the equipment to be bad, but it depends on the arrival Grunssubstanz so the coffee bean.
