I received my pan yesterday. It came quickly triple boxed, thank you for packing so well.
I made a chicken Terriyaki chicken stir fry, followed all recommendations: preheat on medium (I cook with natural gas), test with a drop of water if it is hot, used a little oil, added my frozen ingredients and cooked it all on medium. It turned out better than any of my stir fries before.
I love this pan already.
