KEEPS COFFEE WARM AND DELICIOUS!
I usually use this as my road trip thermos for rugby games. We always travel, usually about 2-4 hours per trip, so after four hours, this thermos still keeps my coffee pretty warm. Also, the casing itself seems pretty durable. I've dropped this thing about 3 or 4 times on concrete from the thermos falling out of my back with no visible scarring on the outside of the thermos. I've been using this thermos for several months now, and the lids and casing are still as effective as when I first purchased it. I only wish they made one that could hold a larger amount of coffee.
