Umite Chef Commercial Quality Baking Sheet Pan Set, Natural Aluminum Cookie Sheet, Warp Resistant Nonstick Baker's Half Sheet Pan, Large Thick Cookie Tray Pans for Baking, Roasting(2 Pack, 13X18Inch)

Put the tray in the oven for the first time and 20m later, heard a loud bang - the tray had twisted out of shape due to the heat in the oven! Terrible quality.

These pans are very good quality aluminum. Bought to replace 25 year old ones and they are the exact quality made back then and the same size. Well worth the cost.

These are wonderful! I didn’t expect them to be this nice and I was excited when I felt the weight of the shipping box and realized that they really are heavy duty baking sheets. I was even more excited when I opened the box and saw how nice they are. They look just like the more expensive brand I had originally planned to order. I felt around the edges underneath and couldn’t feel any sharp edges, so I won’t have to worry about being ambushed later. They washed up easily in the sink. They stack perfectly. They have a heavy duty look and feel, just like commercial pans. They’re large enough to make plenty of cookies or plenty of roasted vegetables. I haven’t tried baking anything yet, but pans this heavy don’t usually warp. I tested them with a magnet just to make sure and it didn’t stick, so they’re not likely to rust or suffer the fate of cheaply made baking sheets. These will probably last for many, many years if I take care of them properly. Using metal against them will scratch them, so that’s usually frowned upon. I keep wooden and silicone utensils handy in pretty containers near my oven/stove so that I can grab those without being tempted to use the metal ones kept in a drawer. For scrubbing off stuck on food, I usually put a wet rag or paper towel over the spot for a little while and then scrape it loose after it softens. Those fake credit card things that come in junk mail are great for this because you can either toss them or wash them after using them as free scraping tools. (They also make great little tools for emergency drywall or furniture repairs when you lack the proper tools for leveling and scraping repair putty.) These pans were a wise purchase. They were nicely boxed, so they would make a wonderful gift.

Great quality cooking trays. Very impressed.

Really impressed with the quality of these pans, they are thick and heavy, nothing flimsy about these anywhere! Great value for the price!
