Looking for reviews and input on Omie Life bento boxes with the insulated container.

Loving the concept of these. DDs love soup, chili, mac n cheese, etc. So I love that I could heat it in the morning and it could be at least "warm room temp" by lunch time. They are not cheap so I am looking for some real life recommendations before I pull the trigger on a $40 lunch box!
