UHUSE Portable Food Warmer School Students Lunch Box Case Thermal Insulated Container, Lunch Box.

I ordered this for our son's school lunchbox as he enjoys leftovers for lunch sometimes, and who wants a cold slice of pizza or meatloaf? This actually works really well! I wasn't sure what to expect since the price was so much lower than other similar things, but it works great and he says the food is still warm at lunch. The seal works great, and though I can't vouch for its true waterproofness, it does a good job. I wouldn't serve soup in it, though. The materials this is made of are cheap, of course--the metal on the inside is awfully thin, but at least it's metal. The lid and all the outside parts are plastic. There is two carrying handles that lay flat that are pretty handy, and there is a small vent, too, to pop open should the heat of the food create a suction that's hard to break. Definitely preheat the container with hot water before putting the food in. Overall, great container.

Love everything about it. I haven’t used it as yet to test the temp control function and thus the 4 stars.
