 SteriPEN Adventurer Handheld Water Purifier By: SteriPen Average Rating: 4.5 Total Reviews: 5 More Information good for travelers  On: 2008-03-04I bought the SteriPEN before traveling to India and Nepal. Three weeks on trains and in modest lodging, using the pen to sterilize one liter of water at a time.I learned that I had to insert it deep into the water, just a little beyond the rod, otherwise it didnt work. I used it 20 - 30 times and it took away the uncertainty about the water. Im taking it with me to Mexico this month. Its lightweight and small, so easy to include. Have not used  On: 2008-01-07The pen seems to work properly, but I have not tested it on raw water as yet. Lightweight but doesn't like the cold On: 2007-12-30Having read elsewhere that the Adventurer was hard on batteries but most people were using rechargeables. I decided to do my own testing using Panasonic Lithium Photo batteries. Thus far I have gotten about 20 liters of purification over a period of 6 days. The only time I have encountered any problems is in cold. For the first test I put the pen in the refrigerator for about 3 hours and tried to use it but it only flashed the red light saying the battery was too weak. After warming it up for 5 minutes with body heat, it performed fine. Another time I left it outside 40F for a few hours and tried it but had the same problem. Again, after warming with body heat the unit worked fine. I was looking forward to using the Adventurer in the winter when filters freeze and chemicals take way too long. After these tests it is obvious that I will have to keep it warm or warm it up before I use it. I think it must really require a big "shot" of power and it is necessary that the batteries are warm to be able to do this. Recommended with qualifiers. Works Great On: 2007-09-17I have used the SteriPEN Adventurer for a week of backpacking in Colorado. Several days involved sterilizing what you would ordinarily call "good" water from running streams. But, several days included taking water from a lake in an area with heavy human use (no human waste management like a pit toilet). The water was obviously questionable and I was concerned that the SteriPEN would not be up to the challange. But, the only way to know was to try it, so I did. No illness at all. Got at least 50 quart sterilizations with one set of two CR123A batteries (non-rechargable). The product and its single LED signals take a little getting used to, but my experience convinces me it does the job. It is very rugged - though I always worried about breaking the bulb. I took no special precautions carrying it. Simply stowed the provided hard shell and poly-canvas carry bag in the backpack with other gear. It traveled without problem.

Well, I did not get sick, nor did he.... On: 2007-08-06After a good friend returned from a tour in Iraq, he told me about a "sterilizing pen" that he had used while overseas. I have to admit that I was rather skeptical being a pump carrying/Iodine using type hiker, but I decided to give the thing a try (swayed by the info that other military folks in my friends unit did get sick, and the information on the Steri-Pen website as to the frequency of illness with the methods of purification I was using). Since its purchase I have utilized the Steri-Pen on two multi day hiking trips, and have felt fine the whole time. Admittedly, I did not drink from any questionable sources, nor did anyone else in my party get sick using other methods. But with the weight being so little and the level of removal claimed by the maker being so high, I felt that this was a great purchase for someone into lightweight packing. I will amend this entry if I do get sick in the future...... Well, I did not get sick, nor did he....
