I really like these containers as left-overs for stuff like lasagna and taquitos so that when I make extra I can throw them into the freezer and my husband and daughter have options to eat while I'm gone for work. I also love them for work in my lunch box because they stack so nicely and really hold their shape! However, today my husband went to put some lasagna in the counter top toaster oven and the lid caught fire! I searched the comments and questions and it seems people say that you can put it in the oven, but apparently not in a toaster oven set to "bake at 350". I'm a bit disappointed with that but overall I do really love this product and would buy it again, just have to remember if heating in the mini oven to take the lid off and use regular foil.The Tins and cardboard covers have been great for freezer meal prep. Small tins - 5 Mini meatloaf's, Medium tins - 5 two serving lasagnas, and with the large tins I have so far made 2 (4 serving) stuffed pepper meals.Tin's hold up well from freezer to oven.Only down side is the stupid plastic lids that come with the tins. What a waste of plastic. If you were transporting serving something not hot and not liquid they would be ok.These were purchased to freeze meals in so we could have nice family meals on our busy nights. The quality is good. The bottoms are flimsy, so unless whatever is inside is really light, you do need a tray or cookie sheet under it when moving it. The lids sealed tightly and I have not noticed any freezer burn. I did wrap them in plastic wrap after sealing just in case.The large size will fit a good sized lasagna easily.I'm not sure if I got someone's return or what happened. The containers arrived, not in sealed plastic, but rather loose in bubble wrap. If you look at the 3rd picture, you can see the bubble wrap has something in it. My hands felt so disgusting after opening them, that I had to go wash them. These were definitely not usable for food. Returned!!These tin foils are a great idea. However, there were a few flaws.1. They were smaller than I was expecting. I placed a 5x7 inch index card and found that as the card reached the bottom the sides were bending up. So the base of these foils is smaller than 5x7.2. When i first touched them I laughed because they were so thin. So I decided to test if they really held a pound or not. I put 1 pound of water in the pan and saw that the bottom of the pan bowed down when i picked it up3. These foils are sharp. The curled rim was rather thin and sharp on the edge. I wouldn't trust it with small kids or clumsy/rushed adults/teens. I was very careful to open these because I accidentally cut myself the first time I used one of the pans.4. It's cool that you can easily flatten these trays out, though I don't know that everyone would find that useful.I forgot to write a review because I've been so busy with work, but I'd like to say I ordered these pans to make food for people at work. I ordered the 50 pack and guess what happened when they came in? I opened it and was very pleased with the perfect size and so I pilot it back in the box because I wouldn't be making the food until that weekend. Well the day came and I was going through, writing all the names on the lids and I ran out..... I was sent 50 pans but only 38 lids... I was very upset. Because I had to put aluminum foil on all the rest of them seeing as I had to make 48 pans. It was upsetting but I made do. Please people count the lids! Idk if this happened to anyone else but it was so last minute for me I had to just figure it out.There is no plastic lids for the large onesI’d prefer these be listed by size rather than weight. They are of good quality.Perfect size for single serving. They made it easy to make single portion casseroles and freeze nicely.trouve dispendieux
