In an earlier review, I wrote that the Geode Rose bottle keeps water cold “14 or 15 hours.” That was a typo; I meant “24 or 25 hours.” I empty the bottle daily, but water should stay cold about 2 days. I gave this 4 stars bc the glossy finish makes the bottle tough to handle and the rubber handle feels light. These points are important bc I take Swell bottles to tennis games. Thanks
