Query: Did not last as expected !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I have had this pan for 2-3 years. This is my most used pan, we use it almost every day. We have been very strict to use appropriate nonstick pan utensils. The pan just flat has worn out !! The nonstick surface never pealed like cheap pans, but the center area of the pan that gets the direct heat in the last month became increasing "sticky" and very difficult to clean. There are no scrathes, but the color has changed. Food also started burning at low temperatures. And heat is no longer distributing. I have a large set of anolon with a lot of add on's -- so I will stick with them for now -- but I will not buy anymore until i see if this happens again. Very disappointed !!!!!!!!!!
