Summary: The capacity is for 20 cups COOKED rice, not raw. Also, the measurements are not US cup measurements so make sure you are using the included measuring cup to add your rice. I used 11 cups of long grain white rice and 11 cups of water and the rice cooked to perfection in the end.
Summary: This croaked after 6 months. You now have to fiddle with it to get it to the cook setting, although once you do, it does work. I'm surprised as I owned one before that worked beautifully for years.
