Dont have it for long to say how long will the coating last but we shall see.you do have to season it like cast iron. I did it once and it was fine going forward. My lecreuset had to be seasoned a number of times I recall.
Recently I switched to Hexclad and as long as the pan seasoned right and temperature is properly controlled it is very nice pan to work with. The handle is the most comfortable one I worked with.
