Sounds like, from reading reviews elsewhere, that these are great for about 2 or 3 weeks and then stuff starts sticking - really bad. Think we'll stay away.

Can't comment on C's pans, but have experience with "Greenpan". Found 2 different skillets at a yard sale. One had never even been used, other looked barely/rarely used... no crud or scratches. For $2 each, took a chance. Both came with nice glass lids. Both became very NON-non-stick after only a handful of uses. I tossed them, but kept the clear lids, which fit Calphalon skillets that had no lids with them.
