So you have to unscrew the knob to get the lid really dry.
Had this design flaw does not, and would have made a decent Tefal there silicone gasket underneath, then the pots were measured by the price OK, especially for young people who have little money and are looking for a "Einstiegstopfset".
But for the money, much too expensive considering what you get.
I personally would not recommend this Topfset further, since it is a significantly better set are at discounters for half 2x a year, which is qualitatively and functionally better. Waiting rather then (when it comes) and to strike there, so since you served better in my opinion.
