I have quite the collection of water bottles, and this is now one of my favorites. First of all, it is very feminine and cute. Secondally, it is leak-proof! I couldn't believe it either, I turned it upside down and shook it around and not a single drop of water leaked. I've had a strangely diffucult time finding a water bottle that doesn't leak. This bottle is now my go to for the gym. I toss it in my gym bag with all my other stuff and I don't have to worry about anything getting wet. It also comes with some cute bracelets. I haven't tried to take of them off yet as they provide a nice grip for my hands.
