Some steam exits above => very good, the kitchen is not a sauna Place in the pan => in the middle Communication of taste of foods from the top to the bottom => Nickel, no taste (test with potato and zucchini bottom to top) Steam boiler which plays its role.
Small annoying thing at the end of cooking, it's a bit broken mouth to take the dishes without having miminnes that heats :) but nothing dramatic, considering the price it is understandable.
