Title: Great for traveling
Review: The this filter goes with the Katadyn Micro water bottle. I use it mostly when I travel and hike. You never need to worry about unclean water no matter where you are. It is an easy system, doesn't require any more work than a normal water bottle and is the same size as a normal waterbottle. I just warn you about one thing: if you change elevation (ie hiking in mountains or especially on a plane), the pressure in the bottle changes and when you open it, water will squirt out at you... but there is an easy solution, open the bottle with the straw in your mouth. I also think that the bottle could use a lid of some sort to keep the straw/mouth piece clean
