I swapped out the momentary switch for a standard on/off switch from Amazon for my Eureka Mignon Filtro grinder.
The tiny act of not having to stand there pressing the button in the whole time you are grinding coffee seems petty and ridiculous but genuinely results in a better routine overall. I am now free to focus on other aspects of coffee prep and as a result the routine, even if just for the short time the beans are grinding, is improved
I like multitasking. What can I say.
That is my understanding! The lowest grind setting on this is easily fine enough for a moka pot. I do not have any espresso experience to say whether or not it would be passable for an espresso machine.
