Sep 5 2009: It's is absolutely great invention and significant product that would save many lives on the time of crisis. the only concern I have is the price/unit which I believe is not convenient for alot of donating individuals and charities as well. Therefore, I would suggest to have a first-step filterazation of the water (externally) before pouring it to the LiveSaver bottle. And using less layers since the water won't be very filthy if this is going to lower the cost & maintain good result. Finally, Thank you so much Micheal & God bless you.
