Produces very consistent super fine grounds for espresso, much better than my electric budget grinder (that I even modded twice to get closer to espresso grounds).
No static buildup at all, really does take about 1min per shot and maybe something like 100s for a double shot. Very precise construction, the folding handle is excellent, quality seems to be very high.
The only point to be careful with is it's fragile when opened, I dropped it from my counter (because the weight distribution is weird with the handle, it just rolled down from near the edge) and it got an instant dent on the threads, even on our relatively soft wooden floor, that I had to readjust with pliers to make the grounds cup fit again. Apparently you can also get replacement parts easily, but I'll see about that.
Other than that, the time it takes to grind, the level of adjustability for tuning up your shots, and the ease with which it actually produces the grounds, is remarkable. Great gadget, improved my espresso experience greatly.
