I have in my sixteen years of "housewife" can test all kinds of pots, and the Diadem series of WMF is by far the best! The pots are quite heavy u. Are thus well on the (Ceran) hob. What I love most importantly, they are super-easy to clean in the dishwasher and the Chromargan looks after like new again. Another tip: the frying pan from this series. Never saw a frying pan with me after all this time still as good as easy to clean.
