We bought this set about a month ago, and have been very pleased. These are heavy bottomed pans that hold heat very well. We were so happy with the set that we already purchased a 5-1/2 quart saute pan to go along with the 3-1/2 quart saute pan that comes with the set. They do discolor, but that's stainless. If it becomes bothersome, we will get some bar keeper's friend.
