First I thought of buying a metal water bottle, but then I began to think: they build up minerals easily and fast and they dent easily; therefore, I began to look for a plastic one. This series immediately caught my eye, and so I purchased it. I have used many water reusable water bottles before, both plastic and metal, but this one beats them all by far. Not only is it an elegant looking bottle, and a perfect shape and size to carry around wherever I go, but the mouthpiece is amazing. I had no idea what I was missing out on, but drinking from this water bottle is extremely comfortable. This is just great.
