We bought this for our daughter to use at school. We have had such little luck with durability and storage with kids lunch bags, and she wanted a way to bring hot food to school. This is a perfect bag. Very little cons about it. The space is big and can fit quite a bit in there. The little storage containers are perfect for child sized snacks, and easy for her to open herself. There is a space for her to put her water bottle inside the bag, standing upright which she loves. We eat a lot of asian food, and she is so happy to have her own set of chopsticks to eat like her daddy. The container that keeps food cold or hot is great, and it works. She took some macaroni and cheese to school and it was hot when she opened it at lunchtime after packing it at 7:30 in the morning. When she came home and I opened it to clean it, what was left inside was still slightly warm! At 4:20 in the afternoon!!
The cons are:
The bag zips, but there are 2 small openings on either side of the zipper. Some things have fallen out, the chopsticks being one of them.
The container to hold hot/cold food is not leak proof, so her hope to bring soup with her can't be done.
No english version of directions came with this, not that you really need it. However, for me it took a photo to show me to pour hot water into the metal container and let it heat up, dump it out and then put in the insert with the hot food to keep it hot.
Really, aside from not being leak proof, these other things are not a big deal.
We will be purchasing more of these bags, since my son will be going to school next year and we would like him to have a durable and good lunchbag.
