Used it a total of 3 months on the road. Never got sick. Some tips, no particular order:
1. Buy one large silk neckerchief, 2 Nalgene HDPE narrowmouth bottles, 4 high-capacity AA NiMH batteries, and a wall charger. The neckerchief is your filter for "floaty stuff" and the Steripen snaps into the mouth of the Nalgenes like it was made for it, providing a watertight seal. Shake instead of stir, and no spilled water! Buy all this and never have to find bottled water in rural China again!
2. Dry it thoroughly before storing! Otherwise you'll get scale (limestone) buildup between the sensor electrodes and the pen will refuse to start.
3. With NiMH 2500mAh batteries, you can purify about 40 liters before a recharge.
4. Note that the Steripen DOES NOT remove harmful chemicals like oil or gasoline from water! To fill your water bottle safely from a source with oil or other petrochemicals floating on the top, submerge the bottle first under the water mouth down, wipe off the mouth underwater, and turn the bottle right side up to fill. Cap the bottle underwater and bring it back out.
