I just bought this pan last week, and I've used it several times. It has a lighter nonstick finish, which doesn't alter baking time. I love it because everything just slips right off it. I now want to buy the 17 inch size. I did notice that there are other websites that offer this same pan at a lower cost. This pan is the sturdiest jelly roll pan that I own. It is definitly good quality. I am going to replace these with my less expensive warped pans that I now own. If it warps like other people have said, then I will update this review.

This is a nice quality pan. It has a sturdy "heavy" feel to it. I have used it quite often and have not experienced any warping. Clean-up is a breeze!

I bought two of these pans more than a year ago and I have had them stain, warp and alter the cooking time for cookies and biscuits. The strange thing is that the very first time I used these pans I was making chocolate chip cookies and one pain stained from the cookies and has never been the same and the other pan didn't. (These pans are not created equal?) Over time, I have also noticed some strange staining in the corners (as the other reviewer noted) and I can't remove it. The warping started several months ago when I had bread in the oven on one of them and I heard that loud bang that we all have heard before. Thank goodness it wasn't a pie. These pans are pretty heavy and maybe it would have thrown the pie off of the sheet! :)

I bought this two years ago. I probably use it once a month for baking. Even though it's non-stick, I had purchased a silicone baking mat since it allows the pan to last longer and cookies don't burn. Unfortunately, I discovered that this sheet is about a half inch too narrow (probably 11" when I needed 11 5/8"). It would have been nice if the full dimensions had been listed on the product desciption.

Otherwise, it's done pretty well. Nothing sticks and it cleans up well except for some condensation that seems to have left brown stains that I cannot wash away.

We built a new house and I decided NOT to move my rusty old bakeware into the brand new shiny kitchen...I bought this pan (among other things) and am very pleased with it. It is very strong, sturdy, and easy to clean.
