Tips beginners mill

For the price and my knowledge one of the ideal entry-level coffee grinders for espresso connoisseurs.
The only drawback so far I can only see the flap of the bean container. This flap can be filled with beans poorly or not at all close. Especially for a bean change that is needed but otherwise the beans trickle out from the container. One can thus manage the bean extract up or let grind the container empty.
Depending on the degree of grinding beans in my machine must be very finely adjusted. Previous maximum is at stage 3 of the 40th
Some tips and instructions to optimize or adjust the grinder there is the manufacturer on the website and in kaffee-netz.de
