I have this pan - worked great for about 1.5 years but then began to "bubble" on the flat surface. Obviously this is a manufacturing issue & Scanpan claims to have a lifetime warranty on manufacturer defects. I sent it off to the factory & they refuse the claim due to lack of cleaning...I work in a freaking research & development department for cookware. I know how to clean a fry pan. Their "claim" is a small area on the lip of the pan - FAR AWAY from the main bubbling issue - & an area I didn't scrub completely because once I noticed the bubbling, the pan is useless to me.This is a complete joke & their warranty "policy" is apparently: unless if falls out of the manufacturer's box in 10 pieces all while catching it on camera with a factory representative on hand, we will not cover.Roll the dice if you choose. This pan is so expensive, for them not to treat warranty claims with the respect they deserve is ridiculous.
