This is true. No other bottle can measure up. I've been using this at least a month so far and I do fill it halfway and put it in the freezer and no problems. And keeps clean longer than other any other bottle I've used. This bottle has a nice think plastic and the narrow mouth is perfect for zero spillage! My looking all over the internet for the perfect bottle has really paid off!
