Query: Not as good as I thought it would be

After messing with the top and finally getting it on the right way, I poured my hot coffee in there and 2 hours later it was just luke warm. I am very disapointed in the way this does not keep coffee hot. I am back to using my old one that keeps coffee hot until the next day. Going to look for one like my old one. I just thought that this one would be good because it was a Thermos Brand and found out not all name brands are good.
