After 2 years experience skillet glue for most foods but using it every day and often 2 times a day so the 25 year warranty that is not the top but since this was not a pan of a lot I see well with others what happens. Even if it sticks I still uses even putting a little oil or butter and it is always more efficient than other big brand stove and she was not deformed at all so it's still a good investment but do not expect it to rest 25 years without sticking;)
