I have used these in the past, especially when I first moved out of my parents house. The first one ever was for a turkey dinner for me and my room mates. I poke holes in the bottom of it with a fork while trying to get at my turkey. It was a mess. It also bent all up and was all wobbly when I tried to take it out of the oven. Forget now trying to put on stove element to make gravy with all the holes .

Recently I bought an aluminium square cake pan. I swear the cake tasted like hot aluminum. I do know that aluminum products can have side effects. I do't' recommend these aluminum pans at all.

You can go to the Thrift or 2nd Hand stores and there are plenty gently used pots, pans, cake pans etc for probably less than you paid for this floppy aluminum one. Then you can re-donate it when your done. Its a win win for me.
