I bought a set of these for myself, then had to purchase a set for my mom and children. They are very sturdy, easy to clean and haven't warped. I have purchased several cookie sheets throughout the years (I love to bake) and these are very nice. I was concerned because of the price, generally the cheaper the price, the cheaper the product. No so in this case, I have purchased ones that after one baking session the pan never sits completely flat again, these have now been through numerous dozens of cookies and still look new. My mom, who is also a baker insisted that I go get more. My children tried to get me to give them my "awesome" cookie sheets. If you use cooking spray this is a good product for cleaning. I have sheets that turn color & get sticky from cooking spray, these have not, as of yet.
I would say this is an average product for an above average price. Having three trays is useful, until you realize the largest tray won't fit in a lot of ovens. The trays look really nice until you actually try to use them to make chocolate chip cookies and the chocolate stains the tray. They are also quite thin which causes them to warp in the oven. If what you are cooking is not very heavy, it will look like the tray is going to fold in on itself. This corrects upon cooling, but is a bit disconcerting to watch if you have an oven light that allows you to do so. All in all, they function as intended to cook food and they were the first thing I saw in the store when I was totally over the whole shopping thing which is why they were purchased, so I can't really complain. If I had it to do again, however, I'd buy the store brand sheets my mom bought a few years ago - those things get used a ton and still look brand new, and they are thicker so that they don't fold up in the oven.
Warped on first use. Disappointed. Expected higher quality. Can't believe its advertised as heavy gauge material
Warped on first use in 350 degree oven. Not permanently but still, I don't expect that from Wilton
I bought this set about 6 months ago and am not satisfied. The quality of the product is ok. I have used the cookie sheets at least once per week and the sheets have a tendency to warp after being in the oven for about 5 minutes. All three sheets have the same problem. The price for the product is appealing but the product isn't.
My son literally bought these today and I've had in oven about 5-10 mins at 350 and the large one is already warped. Washed first, hand dried and let sit a few mins to get to room temp before using. Won't buy again and these will be going back.
