Very sturdy

Solid construction.

High quality

Sturdy and non stick

As others have said, these warp in the heat. I wish that I would have kept the label on the sheets, but I do believe that it states "oven safe to 350 degrees". If you bake any higher than that, the sheets WILL "pop" violently and warp while baking. They stain very easily, and if you happen to get water into the bottom of the pan, the corners will hold A LOT of water and it will make it nearly impossible for the sides to not rust. Truly disappointed with this set.

I've baked lots of cookies in the past month and these pans work great. I haven't had anything stick to them. They do warp a little in the oven, not noticeable but I could hear it. Probably would not use them for pies. They haven't stained, but I have not burnt anything on them. A few people have mentioned rust but I never submerge my cookie sheets in water

Best nonstick pans I have ever used. Made baked chicken wings without using foil or oil. They came out crispy and did not stick to the pan. Cleanup was easy. I just wiped the pan with a paper towel and everything wiped right off. Then I hand washed the pan. GREAT PANS

very nice, will only bake on these!

Absolutely love these pans!!

Trays work great. Biscuits brown on top and bottom.
