We're a little disappointed in making rice.  Last night we made our 1st batch of rice (just 2 of us), and made just a half of the cooker's capacity.  The little vent hole is not big enough, we think, as the energy from the water's bubbles were lifting the lid and causing it to ALMOST blow over.  My husband put a very small stick inside the lid to allow it more air, and it settle down a bit.  However, it looks like a full pot of rice could result in a kitchen mess - we aren't going to try it.  The cooker serves its purpose, now that we know its real capacity.
