I love this, I thought it wouldn't keep my drink warm but it definitely does. I use this for coffe water and more. I fill it up at 7:00 in the morning with 3 ice cubs. The ice cubes melt in about 6 hours but still keeps your drink cold. I don't think it is worth the price because you can get these off brand water bottles. But one good thing is it your drop it, it is easier to dent a different water bottle then the one. It's better metal than other water bottles.
