I love these sheets. I had been looking for them for a while and found them one day here at the best price I had ever seen so I snatched up 2 and they are great. It's so nice to finally have baking sheets that don't warp are large and wide enough to put a cooling rack on with out it hanging over the edges but still fit my 30" oven. We are currently clubbing our basement and including a little kitchen area. I'll be back to get a couple more for my oven down there. Very happy with these.
