Hi, I've used two pans so far.  One to boil water and one to fry a couple of eggs.  The pan that I boiled water in after I was done had small brown spots at the bottom of the pan, which I thought was very weird for just boiling water.  The pan I fried the eggs in was hard to clean and still has marks on the bottom.  I read about the care of the pans before I used either pan.  Not sure if I'm liking these pans for the price I paid.
