How the hell did they managed this thing. The main con with all filters is that it takes bit of time to filter the water. 8 seconds is unprecedented. The best part is ghats it is basically like a portable water bottle. You can take it while you are hiking and drink straight out of some fountain or river without much worry. The speed may have sacrificed some quality. But if the water source isn't that polluted GRAYL GEOPRESS should do the job.

The best part is the price tag. It's a great deal compared to what you can do with it. Awesome Hunt!
