Non stick pans will usually last a few years if you avoid scratching them and overheating them. Anything over a medium high heat (6 on an electric stove) will cause the coating to develop microscopic cracks that eventually cause the coating to fail. I buy homichef from Amazon because it has a solid base that holds heat well and replace them as soon as eggs start to stick. Also, don't wash them in a dishwasher. The detergent and high heat will cause coating failure quickly. I generally just wipe them out with a wet dishrag and warm water.
