Like any tool, a thermos can be your best friend or your worst nightmare. Make sure you choose the thermos appropriate for your situation, or you're going to end up in world of hurt. I think the lesson we can all take away from this is to trust your instincts, go with the gut feeling you get when you hold the gear in your hand....you're probably right...you've lived this long after all. And remember, looks count for half your score...its important to look good as well. Functionality is only half the equation.
