"Sturdy, heavy-duty baking sheets"
Couldn't be more pleased. These baking sheets are good size, don't warp in oven heat and do what they are supposed to do. After years of using a variety of lighter, supposedly non-stick cookie sheets, I was delighted to find these. They are heavy enough not to warp and that can be cleaned easily without a hard-to-identify coating that adds nothing to value. Will look to Chicago Metallic when I need bakeware.

"Jelly roll pans"
Heavy duty non-stick pans are high quality and great price. Cooling rack is a bonus.

"Solid, Heavy Duty Nonstick Sheets with Wire Rack"

I could not be happier with this set of two sheet pans with an included cooling rack. As noted by some of the other reviewers, this set of sheets is quite heavy and very solid. I have used them now for about a month, including some service under the broiler and extended use in 450 degree ovens, and have not had any problems with warping or the like. They are still flat and true as the day that I purchased them.

Though I normally follow the recommendations of America's Test Kitchen and Cook's Illustrated for equipment, I purchased this item before I saw the November/December CI article on sheet pans. In the article, they give the Chicago Metallic pan a "recommended with reservations rating", stating that it had warped slightly under high heat. They recommend the Lincoln Foodservice half size heavy duty sheet pan instead(note that this $15.40 pan does not include a wire rack, which you would need to purchase separately).

Notwithstanding their rating, I still back this item whole-heartedly and personally have no inclination to upgrade to their recommendation. I have found that many of my recipes do in fact require me to have a second sheet pan on hand. Given the great price on this set, and my experience that they are very heavy duty and have not in any way shown they will ever warp, I can easily back a five star rating on this product. I bought a second set for my girlfriend, who also loves them.

"Good value for professional products!"
I bougtht the pans and cooling grid! I agree with the others that said you need to remember they are heavy~ in a good way!! I've always bought cheap pans and had them warp, etc. I like these pans very much! I do have to be careful when cutting on them (if making bars or pizza!!) but otherwise, they are worth the value price!! I also really like the cooling grid! Nice size!

"Fantastic, heavy duty jelly roll pans"
These pans are nice and heavy, with good sides to roast veggies or toast up some fries. Nothing sticks. I burned only one batch of cookies, because I forgot which timer I was using for which batch. I can't believe anyone would blame burnt cookies on the cookie sheet! I also can fit two batches of cookies onto the cooling rack, and the pans and cooling rack all stack into each other for easy storage. I ordered three more sets!
