Input:
This pan warped within 20 uses and the manufacturer's lifetime warranty is misleading.  We've used this pan to make pancakes on the occasional weekend for the last year and were appalled to find that it will no longer lie flat on a cooking surface because it is so badly warped.  When I contacted the manufacturer to take advantage of the "lifetime warranty", I was informed that their warranty doesn't cover warping.  I imagine that there is a whole host of other defects that their warranty doesn't cover.  While it is true that they offered to "evaluate" the pan through a "warranty evaluation process" that involved me finding a box to package it up, finding a post office to ship it, and waiting up to 4 weeks for the manufacturer to respond with the likely answer - we don't cover warping.  This is a great example of the risks of not buying local from trusted providers.  Had I purchased this from my neighborhood Sur La Table, they would have simply exchanged it.  I certainly won't be purchasing any more All-Clad items, nor will I purchase kitchenware online anymore.
