I just got a new stove with a convection oven and was looking for three large cookie sheets with no sides. The oven instructions said cookies would convection-cook better on sheets with no sides than sheets with low sides. I wanted to load all three shelves up at once with cookies. I bought one of these jumbos and boy was I impressed. First the size; the dimentions given are dead on--15.5 x 20 inches. The turned up grip edge makes the actual cooking surface to be 14-3/4 x 20 inches. This is perfect for my oven. This gives me about 1 to 2 inches all the way around the sheet so the air can circulate as it should. Second the weight; this sheet is heavier than I thought it would be. I thought the size of this sheet would make it flimsy. Not so! I was impressed with design which gives it plenty of ridgidity. This is a quality insulated cookie sheet with non-stick coating on the bottom as well. After examining the quality on the first one, I bought two more. I can recommend these highly. Be sure to measure the inside of your over before you buy and use the cookie sheet dimentions given above.

I use this cookie sheet constantly. It's a great size and it cooks evenly. The only problem is I have a hard time grabbing it out of the oven with an oven mitt on. I wish the lip was just a little bit deeper or had a rolled edge or something. It's a small inconvenience though because overall it's terrific.

Being a strong believer that you 'get what you pay for', when I decided I wanted a superior quality cookie sheet, I went directly to a Farberware product - and Farberware definately did not disappoint with this cookie sheet. Firstly, it's huge, so it easily bakes over a dozen very large cookies at a time. And, it bakes them beautifully - the entire pan baked evenly, and the bottom of the cookies were perfect! This is, hands down, the BEST cookie sheet I've ever owned. Now, I have an incredible cookie sheet to bake my incredible chocolate chip with pecans cookies on! Excellent, excellent product!

This is a replacement of what I already own. If you are baking Christmas cookies, this product is a must! The "double wall" helps to avoid burning the bottom. Highly reccomend. Once you use these, you will throw away all your single layer baking dishes.

Having recently used this as part of the holiday baking equipment, I got a full run test to base the review on. This is a heavy weight cookie sheet, nothing cheap about it, it does cover a full rack in the oven and it's non-stick coating so far appears to be quite durable. Cookies did come off quite easily, even sliding off in many cases, handy if you are at the right location and time to remove them, that is. This would be great to cook a large pizza on, as it has the size to do the job. It has been very easy to clean as well, as you would expect from non-stick coated bakeware. You do have to keep a good grip on the this rather slippery sheet though, as it wants to slide all over the place. To resolve the sliding issue, make sure to place ONLY on a flat surface and use a silicone baking glove or mitt to move it while the sheet is too hot to handle. This sheet is ultra-efficient for the busy cook in the way of baking so many things at once, just about double the normal size cookie sheet capacity. The big problem with this sheet being it's tendency to develop hot spots, which means the full sheet of cookies is likely to be baked unevenly, especially those that are closer to the edge burn a bit, meanwhile those in the center are far less done. Trying to rotate this sheet half way through baking time doesn't entirely resolve this issue either, as well as that being no small task, given the sheet must be pulled all the way out to be turned around, given it's size. If you are baking cookies or similar, this sheet is probably best suited to those with convection ovens, as they have less tendency to produce those hot spots. For the rest of us, this sheet provides a great tool for supporting large disposal aluminum baking pans, items that are very large, such as french bread and also to use as a drip pan underneath the messy and drippy bakers like pies. Given this is an insulated baking sheet, I really was so disappointed with the burning issue, but all in all, with the tasks it is suited for in mind, I could definitely recommend it.
