Bests & Worsts Reviews from Amazon

My daughter recently wanted to start having leftovers for lunch instead of sandwiches so we ordered her this. I read other reviews stating that their food was cold by lunch but took a chance and here is what I found. One, macaroni and cheese is almost cold by the time you put in on the dinner table, so bad choice for this. Two, you have to properly heat the thermos. I add really hot water and screw the lid on. This keeps the water hot and also heats the lid so when you put in your hot food it isn't losing heat by warming up the lid. I have put lasagna and meatloaf in the thermos and four hours later it is still warm. I microwave the food till it is hot then pour out the hot water from the thermos, quickly dry, and add food. There is no such thing as a product that will do these extra steps for you. If you want a conveniently small little thermos to fit in your lunch bag you have to treat it like a small little thermos. The extra prep time (which takes just minutes) insures a warm lunch. I would definitely buy this product again or give as a gift. Update: My daughter wanted to bring juice to school so we tried two methods. First we filled with water and ice and let it sit for a few minutes then dumped the water and filled with juice. 5 hours later it was still cold. Second we just filled the thermos with juice and then put it in the fridge overnight and juice was cold 5 hours later. She just loves this product.
