FWIW....a few years ago, bought two Calphalon 12" omelette pans (#1392) at BBB. About $70.00 each as I recall. Used them frequently. Even though they still looked fine, they began to stick a bit -- made it harder and harder to make my fried rice and soba noodles. (This is the one: http://www.bedbathandbeyond.com/product.asp?SKU=12112963)
Sent them in to Calphalon for warranty consideration a few weeks ago and yesterday received two brand new ones. No hassles about receipts or usage or anything, they just did it.
I regard as excellent service. Suspect I may be buying more Calphalon stuff.
