Had a little difficulty to understand the valve closure. In my previous pots, the safety valve came out and was not allowed to rise above a certain mark. Here, the safety valve is only to cover the edge and if you then reduced the heat, it was a little later again and the pressure was no longer present. Once I had not reduced enough, because the steam whistle laustark from my fright. So to keep the measure requires at electric cooking a little experience because of the residual heat. With gas stove is no problem. Otherwise, the cookware set is very solid and can also be used for normal cooking because the supplied additional cover.
