Familiarity: I've put it through the wringer
I've found these to be great on some ice climbing expeditions in Alaska. You no longer have to worry about you water freezing at night. I also use them as a pre-thermos for ice climbing days. The first round of hot liquid goes in one of these, then a spare thermos for later in the day.
