penguinzI actually own one of these. A nice grinder for coarser grinds, like for french press style coffee. I am not (yet) able to set it up for espresso style coffee. I own it for about a year now, and no problems yet. It feels sturdy, although a lot of (quality) plastic.
rhinocerosbladderFor about three cups' worth (according to this model's measurements), it takes me about a minute and a half of just grinding without breaks.
