This is my third set of scanpan cookware. Despite the claim that you can use metal utensils the surfaces will eventually scratch and with lots of use lose their non-stick characteristics. Before anyone claims I may not know how to properly clean them, let me say I followed scanpan's own instructions to use barkeepers friend from time to time as tiny burned particles can get stuck to the pan. Overall love them and the HAPTIQ pans are beautiful. BIGGEST gripe is that they don't ship to Puerto Rico despite it being in their dropdown!
