The Greatest Water Purification System Ever
I spent Memorial Day hiking in the San Gorgonio Wilderness with my wife and a friend. It's always beautiful there but this trip took a turn for the worse when I found that my water filter had cracked. This happened in a dry year when water flow in all the creeks was pretty low. Happily, some friends shared their steripen with us and I was amazed at how quickly we were able to purify water with the UV light. It takes about 45 seconds per quart. They had purchased the full system: steripen, pre-filter, and Nalgene bottle. It weighed considerably less than my filter even with batteries--under a pound. I'm sold and am purchasing my own. You can get the steripen and prefilter (good for removing particulates) separately, which I will since I have many Nalgene bottles, but if you are looking for a good all in one purification system, this is it.

Worked for me
Took my SteriPEN for 8 days in the Smoky Mountains. It worked every time and must have done the job because there were no ill effects. Do use lithium batteries however.

For anyone having problems I found this at http://www.backpackgeartest.org/reviews/Water%20Treatment/Ultraviolet/SteriPen/Owner%20Review%20by%20John%20Heubi/

I was able to determine that the extended outdoor use seemed to create too much humidity within the unit and caused this malfunction. The malfunction occurred with a much greater frequency during periods of extremely high humidity and periods of extended rain. I was able to "fool" the unit when I got a red light by waiting for the indicator light to stop blinking and then placing the unit in the water, just as if I were purifying the water. Then I would pull it out of the water, just as if I had completed the purification, then push the button again. The SteriPEN would then work just fine for any number of uses. I am certain that this would not even be an issue to anyone using the SteriPEN for weekend or week long treks. The problem also goes away after the unit is in a controlled environment (inside) for approximately 1-3 days to get a chance to get completely dried out.

SteriPEN Purification System Pack
The product did perform as describe. I order two sets of the Lithium Ion battery from another source, one set worked and the other did not.
After a week of constant use, about 6 times a day, it needed a new set of battery. Rechargeable NiMH battery also worked in the unit.

I purchased the combination set with the bottle and pre-filter. The main advantage is the fileter adapter allows the SteriPEN to be inserted into the bottle and form a water tight connection. This makes it easier to shake or swire the bottle without worrying about spilled water.

It took me a while to figure out what was the sediment filter. I thought at first it was missing, but it was the funny thing sticking out the middle of the adapter. Removing the filter from the adapter allows the SteriPEN to be tightly inserted into the bottle. For most purposes, the filter serves no useful purpose, so I just put it away for safe keeping.

I used the unit to purified all my drinking water in Inner Mongolia and any water used to brush my teeth in any hotels in China. At the Beijing Airport, when leaving the country, it did raise some concern about what the device was, and added an extra step to the out processing when they attached a photo of me with a x-ray picture of the unit.

I will take the unit on my next back packing trip to truely purify my drinking water. I have never been sick from just using a water filter on previous trip, but this unit is convenient.
