Quite good-not great

I bought this set because of the many enthusiastic reviews, but now returned.
The pots look good and it is a very good selection pot, the handles remain cool indeed. I am dissatisfied with the rather slight material quality: on my induction cooker work the pots not very good. The heat is very non-uniformity eternal up and down. The stove turned even once due to non-recognition of the pot at a low temperature.
The soil has a tendency to discolor and the rivets seem to stand out in color after 2 times will use what I can indicate subsequent material problems.
I can imagine that this cookware set quite good works in other herds and simple claims. I wanted then but a set 'for life' and that it is not for me. Now have WMF acquired in the offer ...
