I really liked my Bobble Water Bottle when I first got it, mainly because I liked the attractive design. After using it a while, I found that it's not all it's cracked up to be. While the idea of drinking clean, filtered water is appealing, the Bobble filters are pricey and kind of a pain to replace on such a frequent basis. Also, drinking from the bottle is loud because when you drink through the mouthpiece, it contracts the whole bottle - which is made from really thin plastic. The bottle does not fit into a standard sized cup holder, so using it in the car, at the gym is basically fruitless. Don't waste your money on the Bobble.
