But with the last two purchases Sep 2017, the pans barely lasted 6 months as far the non stick properties are considered

This was a gift and If I could return for them I would, its been over 8 months and this green pan is useless, everything burns or sticks.

I have had this pan 5 months

Since 2015, on an average I have to replace the green pan every 8-9 months

good pots, 6 months use and no scratches.super easy to clean.

And now, three months in, these pans are impossible to get clean.
