I'm happy with all the cooking features of this range, but I do have two negatives.  The stainless was advertised as smudge proof, but it is not.  The second issue is a strange spot that has appeared on top of one of the burners.  It looks like, but does not feel like, a scratch.  I have used two different pans on the burner, but both of them are smooth bottoms and would not have marked the burner.
