I couldn't ask for a better pour over brewing device then this. Heats the water in the top reservoir, then drips through the coffee into the bottom chamber with the ice, and the finial product is outstanding. A little trial and error at first to get the amount of ice and a coffee to still have a strong and robust taste. But I will never need to buy a Ice coffee bev anywhere again, I can produce a magnificent whole pot at my finger tips. I love coffee and this has completed me....haha.
