OMG! This bottle is totally and completely worth the price. I literally have it with me 24 hours a day as it is the perfect answer to the issue of keeping hydrated, especially if you exercise or work in hot climates or need to keep warm during the winter. I have it next to my bed at night and in my car when I drive anywhere and in my bag when I go to the gym. Fluids stay cold (or hot), soda never loses its fizz, for 24 hours or more. And it is good-looking, plus light and easy to carry. This bottle is awesome and a real bargain for the price.
