Frankly, I have purchased the pans mainly because of the red dot. Unfortunately, this does not at all. If fat is poured into the center, it goes directly to the edge. The fried food is faster in the middle even when the margin. Previously I had a pan of Aldi, with a green dot on the handle, which was red with optimum heat and otherwise the pan was great. Unfortunately, it is not suitable for induction, a shame. The material of this pan and the free processing itself is ok, about 3 star.
