Use I do it for French press and for that she gives very good grinding results. Whether it is now also suitable for espresso I can not judge because I do not drink coffee, but intended for mocha jug.
Processing I find also very good. One has to just be aware that this is a mill for the household. After 20 sec. Is one of the grinding mill a break. In my case, not a problem since I always for 2 cups of the coffee grind with 4 sec..
The taste I can not see any difference to the hand mills. I like it.
