this thing keeps stuff hot hot hot for a long long long time.
you think: that's what a thermos should do! why is this joker only giving it 3 stars?
1. the inner cap is not very strong and you really have to pay attention when screwing it in or it jsut over-threads itself and pops loose. not a terrible thing, just a slight annoyance.
2. after a few weeks of usage the seal (wherever it may be) broke and air with a tiny bit of liquid got in between the stainless shells. that means the heat gets transferred straight to the outside environment. and all you scientists out there know that means room temp coffee.
it was a great great great thermos... while it lasted
