Bests & Worsts Reviews from Amazon

I have used my Gotham Steel 11-inch skillet nearly every morning since my purchase 3 months ago. I prepared the pan as per instructions, and have used it faithfully following suggestions in other reviews and from the manufacturer. I only use it for my egg-white omelets - same EVERY day. I saute some spinach in butter, add egg whites, and top with avocado and a small amount of diced meat. I use medium heat (lower heat than with my other omelet pans). This has worked perfectly until a week ago. Now my omelets have begun to stick. The skillet still cleans up well, but the omelets no longer slide out perfectly as before. I wish the perfection had remained. I still will use my pan, but wish it had lasted longer!
