I am impressed with this duo set of GreenPan cooking pans. I absolutely love the fact they are made with safe materials for my family. I have not used any other pans, since I got these. I have not had any issues with sticking or burning.   The only improvement I would make to this set is to include lids for the pans themselves.  I would absolutely recommend this set to anyone looking for a quality, safe cooking pan or pans.  They sit flat on the stove top and fit perfectly within the size range.  I find the shape of the pants, with their upright sides, unslanted,  Perfect for my cooking needs. The quality and durability of these pans is remarkable. They are well made and feel heavy duty. Perfect for this home of ours.
