Fantastic water bottle from Grayl

This water purifier from Grayl is awesome. The whole thing came in good packaging with great, clear directions for use, cleaning, and storage. I bought this as an emergency kit option as well as for hiking and even future hunting trips. It operates as it says it should and is not at all complicated. In an emergency situation one person could drink two gallons of water per day for a month with just this one bottle. In the field hiking or hunting, you can pack this lightweight bottle and simply use local water sources to drink from rather than take a bunch of water in with you. As long as you know of a local water source where you're going, you are set. I will likely be taking this on business trips to other countries where water can sometimes be questionable at best. Overall, a great buy and I will likely be adding at least one more to my collection for the backup of the first.
