My only suggestion to the mill so far: Here's a little marker system would not be bad to restore once found freeness quickly.
The mill has a very small "dead space" of a few grams, so that the flour milled always very fresh coming from the machine directly into the filter holder and one uses no old, stale flour. The operating sound is pleasant and not too loud.
The timer works very well and is practically, tap = single serving once, tap = double dose twice. The new 2013er version of the machine even has a dial on the front, over which one can set the timer for the amount of coffee comfortable with the old version, this setting is somewhat impractical attached to the underside of the device.
The mill operates fairly clean, it's next to a little flour. Cleaning is easy, from time to time wash the bean container, the grinder and suck a few "Grindz" by grinding.
Overall a very good device for the perfect home-espresso, where you will last a lifetime. Good also for everyone who wants to often times change the grind.
