i have used only a few times.  So far so good, but the metal thickness is thinner than I thought it should be. lids are problematic. When removing a lid with steam on it and resting it handle side down,  the liquid from condensation runs to the metal edge and leaks through onto the surface below. It also builds up on the opposite side edge and forms a scum when placed back on the pan for continued cooking. Will update on durability at a later date.
