Title: frustrated wtih design
Review: We really love the way this product keeps drinks cold however, the design of the top is poor. The thermos has rolled off my 6 year olds desk twice and the hinge area of the lid has broken both times leaving the straw uncovered and the lid useless. I have replaced it for a third time but won't send it to school or on field trips. The company didn't seem too concerned about the design flaw either, but was willing to send me more replacements parts for a cost with shipping and handeling. I've spent more on shipping than on the original thermos.
