Seems well-constructed, and so far the non-stick surface has held up, though it's only been about 6 months.Unfortunately, the browning on this pan is not consistent. After about 6 months the scrambled eggs started to stick. There's an inner circle of maybe 6-8 inches that browns really well, and everything outside of that is much cooler.
