h: I travel and live in the desert so we always carry water in case we break down or have a flat. Plus we prefer to drink water. We drink tap water at home. Bottled water is convenient, I can take it with me when I bike, or my husband takes it to the gym. Plus, I don't have to worry about the container leaking as it has with the rubbermaid (and other brands) containers.
I generally refill the plastic bottle several times.
