I have been using this machine for a few weeks now. I make smaller portions during the week, so the 1-4 cup feature works great.  Another option is being able to brew strong coffee without having to try and add more coffee for fear of overflowing grounds. Warming feature is my favorite, being able to keep it warm without it burning and tasting bad. The one thing that I did not care for is the time it took to brew a pot, a lot longer than most.
