In the picture you can see the degree of grinding, which has only just fit for the E680. At the next Mahlgradraste the sieve clogged. But you can very well see the big chunks and very fine particles. To prepare a proper espresso thus unsuitable definitely.
Unless you can live with a too rapid flow or use a machine with Crema Seven.
On the whole, for a hand mill with the man drip coffee grind would definitely useful. partially suitable for a filter holder, if you want to refer Cafe Creme. Espresso ... well. There's a lot of luck and often leads to non-reproducible results.
