When I got this waterbottle I was a little disappointed. The bottle is sharp looking, but is made out of very thin steel. I can easily squeeze and bend the middle of the waterbottle. Just the other day i dropped it in the kitchen, and not to my suprise a huge dent was in the top. Now I am very active person, so what if I would have dropped this when I was out hiking or climbing? This is a good waterbottle for the office, not the outdoors.
