Coffee is ok, but nothing more. When the lid after filling will not be pushed down correctly, it can happen that too little, the valve opens. Consequently, the water overflows into the filter and the coffee is just like Grandma, louder "grits" in the coffee. The filling area is so narrow that's not enough space during filling and the "chunky" to pot.
So I buy this device a second time, but my wife wanted the thing. Probably because of the optics. best regards Rainer
