Day one, from the porch to sink for a quick wash and straight to the stove.  I could not wait to use them.  Since having these skillets, we have used them multiple times.  We have cooked things that would normally sticky like cheesy eggs, salmon and catfish.  None of them items stuck and they all came out delicious.  The fish came to a beautiful golden brown without over cooking.  These are now an everyday use in our household.  STRONGLY RECOMMEND!!
