~I do have a fairly extensive collection of anodized aluminum Calphalon, collected slowly one piece at a time...
Funny I wont touch that stuff with a 10-foot pole.
ANYTHING that is coated will eventually lose it's top-most layer.
Buy once, buy good quality and buy what endures "forever".
Most of the kitchenwares sold are crap and intended to have you keep coming back to replace them. No thanks.
Learn to let go. It's OK to throw stuff out, especially when it has become defaced, non-operative or fully or partially defective. You WON'T need it someday. You can get good quality stuff rather inexepensively, RIGHT NOW! Changing one's mindest is only ONE thought away. You just have to WANT to.
Remember, saying "I can't afford it", 90% of the time menas "it's not important to me" Having hundreds of thousands of dollars in the bank and living in tatters is NOT living well.
Having 10 POS articles is NOT the equavalent of having ONE good done.
EVERYONE deserves GOOD QUALITY AND PERMANENT THINGS.
