will have to use cooking spray because food sticks to this sheet

This may be an ok cookie sheet, but I'll never buy one again. It just took--literally--40 minutes for me to get the glue off the sheet from the manufacturer's paper ID/instructions. Usually these sheets attached with 4 points of glue are easily rubbed off. NOT on this cookie sheet. Took forever to get it off. And the truly annoying thing was they could have put this piece of paper on the backside of the sheet where it would not matter if a residue was left. Instead they deliberately put it on the area of the cookie sheet used for cooking. This may seem minor, but it's the little irritating things that make a difference when overall the differences between cookie sheets are minimal at best. Change the glue and/or use shrinkwrap to keep the info sheet in place instead. And now the cookie sheet has scratches and probably damaged finish due to the scrubbing required to get rid of glue. Will never buy from Doughmakers again.
