The burrs are really tiny, and I'm surprised it even works some days.
I shimmed the upper burr out to allow finer espresso grinds using some SS washers.
I get a... useable grind from this. Most of it is too course, but the finer stuff is about right.
On the whole, better than doing it by hand, but really only good for drip.
As soon as money allows, I plan on replacing it with a real grinder.
