I just retrofitted my basic hand crank mill with a 10mm nut, and drove it with a drill. It's so much faster now, but I do wonder if there's actual properly motorized versions of what I just did.
I have one of these too. I concur it does a fine job.
Jokes aside the only negativity I've heard about these is they are not fine turnable enough at the lowest end of the scale.
I find I can get an excellent shot with good crema from most beans, but there are still a lot I feel I could go finer on to get a better result. Or just the beans suck.
I have one of these too. Actually, I have two, I picked one up second hand for decaff.
First world opulence for fifty quid!
Interestingly, the second hand one goes a LOT finer than the new one.
I normally grind between 2 and 6 depending on the bean with the first, but the second one if I take it under 8, it happily chokes the machine.
So I wonder if there is mileage in adjusting the burrs inside (which Sage are keen to tell you not to do!)
