I regret buying these.  Everything sticks.  Either a little or a lot.  This morning I was making hashbrowns.  Half of them stuck to skillet.  I had to, midway, transfet the hadhbrowns to my other non-stick.  I do not use high heat.  I keep it low to start.  Then as it cooks. Sloely I will raise the heat.  
 But never on high.  I have an electric stove.  Do I am very annoyed because these skillets are not inexpensive.
