It's definitely a very cute water bottle, but it's main feature I would say is that it's leakproof AND can store either iced or hot drinks. So really versatile. The strap, I love the idea but it is a bit short even for a short person like me (160cm). Still I would say it is useful if you don't mind the bottle hanging a big higher on you. Aside from this, I love the opening, you press the push button and lid goes up, no unscrewing or risk of dropping the lid while at it. Worth the money!
