The only issue I have is the brew strength with the beans. You put it on strong brew and it doesnt really have the strength of strong coffee. And yes I keep it cleaned out with the brush that came with it. I guess I will try espresso beans to see if there is a difference.

The awesome part about the coffee pot / is the pot itself. I can fill it full and go to pour coffee, water and it doesn't drip out of the pot at all or leak down the side like most coffee pots do.
