I am fascinated by FLOW and will consider ordering it. Here is a link to a water bottle that I gave as a gift for Christmas. I love drinking fresh water - until recent years NEVER bought bottled water but then I learned how damaging some of the chemicals in tap water are (such as chlorine and flouride, two among other neurotoxics found in most municipal waters.) With this news I switched to bottled "spring" water but have been quite torn recently b/c of the problem with the plastic bottles.
Then I received an email from a local 501 (c)(3) that promotes the outdoors and it was this great water bottle that solved several of my problems. From my limited knowledge it appears to be an earth/water friendly device.
Thanks so much for this thread Dan.
