Wilton® Premium Nonstick 17.25-Inch x 11.5-Inch Cookie Sheet

The finish started bubbling and flaking off after first use

Received the large cookie sheets as a gift. It popped the 1St time i used it and stayed warped

I bought this from BBandB because I like the 12 Muffin Pan. But this warped very badly on the first time of use. I thought that this would be a great product from prior experience with the muffin pan. But because it warped the browning was uneven and some juices from the meat and veggies collected in one corner. Just a hassle.

I like all of wilton products. Nonna stick bake everything wonderful

have used this product a handful of times and every time it warps like crazy. If the items I'm cooking don't stick to the pan, they slide to one end or the other.

Every time it goes in the oven it begins to pop and twist out of shape. DONT BUY!!

First time I stuck them in the oven, they twisted out of shape. One of the corners popped up about 2-1/2". Same thing happened with the lighter, less costly versions, so I figured if I upgraded to the supposed top of the line, I'd finally end up with a quality product. I guessed wrong. Tried to upload a pic, but won't take.

The sheet became more and more with stain that i couldn't take off. We going to finally throw them out. I brought the 3 pc set.
