Query: Coffee stays hot for hours

This the best coffee thermos I have ever had. It keeps coffee hot for at least two hours. I got the recommendation for it from a friend that claimed he drove from Columbus, OH to Charlotte, NC and his coffee was still hot. I only took a two and a half hours' trip and was impressed that it kept my drink hot the whole way. Well worth the price!
