Query: The little thermos that could

My daughter has used her Foogo almost every school (and now) camp day of the year. It is by far the best lunchbox thermos available. It fits perfectly into her square-shaped PBKids lunchbox. As other reviewers have pointed out, the portion size is just right for a child. Please note that I handwash it after every use. Takes very little time and has kept the thermos in mint condition.
