have be use the rice cooker for a few week by now . so far we have use it for regular white rice cooking . no problem at all . it produce soft and puffy white rice every time . try once on porridge , the result be not very satisfactory . the only complaint we have be that the non-sticking coat inside the inner rice cooking pan have be moderately scratch at arrival . the reason be probably that the factory simply put the measure cup and spatula in a thin plastic wrap and place they in the cooking pan . as a result , the scratch be make during shipping . if they have use some foam wrap instead , it would not have cause the scratch . I be surprise that this top-ranked rice cooker maker would not have think of this issue .
