Get This Hand Warmer - I'm a teacher, and I ordered this because our classrooms are SO COLD in the winter. I now have four of these, and they keep me warm when I'm sitting at my desk; I got the extras so that I always have one ready for recess. I don't even have to turn it to the highest setting because this thing gets so warm! If I'm just sitting inside, I keep it on the lowest setting, and that's perfect. You should definitely get this if you're someone who is always cold or works in a cold place.
