Input:
The biggest problem was the instruction manual which would be better if it emphasized how to use rather than the warnings and multiple languages.  It  did take my wife three days to finally master it but it has quickly become  a part of our "start of day."  One apparently good feature I  didn't see mentioned is the fact that the unit lets water by-pass the  coffee to avoid the "bitter ends."  I wondered how efficient the  machine would be from the standpoint of transferring the coffee from the  grinder to the filter area (you don't have to use the metal filter--paper  works just fine--actually, most of the grounds do make it to the basket  area.  You do have to accept the fact that the parts have to be rinsed  before the sink or dishwasher--it is a little messy but the coffee tastes  better than that from our older non-grind models.
