Familiarity: I've used it several times
I had originally purchased the orange one in the liter size but it had no handle. Instead of sending it back I gave it to my boss as she's a Denver Broncos fan and it's a very similar color. So I bought the half liter in green and I use it often. It will keep coffee hot for about thirteen or fourteen hours tops. I don't have a clue how long it will keep things cold as I bought this specifically for coffee. I usually carry it in my lunch bag and there's still plenty of room for everything else. The lid doubles as a cup and the stopper is designed to pour through when opened a couple turns. I've had it dribble on a couple occasions but I still like the size and design.
