A must if you travel and like cold or hot water
I was traveling out of the country with my mom, who wanted some hot water to take on the plane, so we filled one coldest water bottle with hot water and the other with ice cubes and water. We arrived at our destinations and went to bed, when we woke up the hot water was still hot 12hrs later and the cold water still had ice cube in it and obviously was ice cold. Great buy for sure.
