I have enjoyed using this skillet for many years. But it was time for a new one and I was so excited to try it for French toast only to find the temperature would not hold as indicated on the control. The toast should have been fine at 325 degrees.  When it would not cook at 350, I slowly turned it up to 450 where it began to cook but eventually completely turned off.  I am very disappointed and now will figure out how to return the skillet.
