I first saw this on Leo Laporte's TWiT podcast network and had to get one for myself.As long as you dont grind the grounds too fine you'll be fine.Also don't use boiling water, try 200F water instead. Boiling at 212 will burn the coffee and make a cruddy brew.Fast, easy, user friendly, plenty of cheap filters out there, easy cleanup!You gotta try this one for yourself.
