Lot's of static, significant grounds on the counter, tends to clog.
Having used the Braun burr model for several years I was looking for a step up. I almost always use a French Press, and don't currently own an espresso machine, so fine grind wasn't a consideration. My only real complaint with the Braun was that it had trouble with the intake clogging on very oily beans
The Mulino was a real disappointment. Claims of "anti static" are ridiculous, it has at least as much as the Braun if not more. It clogs worse and needs almost constant shaking to get, say, Peets beans down. The mess on the counter is significantly worse.
The grind is pretty good (of course for the press I'm using the courser end of the scale). It doesn't grind as course as the Braun would but I prefer it a little finer anyway so that isn't a problem for me. The resulting coffee is great, but overall the grinder is a real pain to use.
I'm at the point now where my wife is asking me to make a change because the grounds are getting into the stove! People seem happier with the Maestro, but I haven't heard if it is much better as far as the clogging problem goes.
