some of us are (very) slow drinkers but still want hot coffee. i usually make my coffee at 9am and don’t finish it until just before noon.
granted, i don’t have one of these tumblers. i do make my coffee in one of their camping french press thingies though, then move it to a different thermos vessel for drinking.
I got a Stanley classic trigger a few years ago because the job I was in was so frantic I'd never get to drink a hot drink hot otherwise. It's been doing we great since.
I can't understand collecting the damn things though!
