    This product is extremely unreliable.

    I have given them the benefit of the doubt for too long, no more will I... We depend on water too much!

    I have to say after taking this on a recent trip, it worked incredibly well and was very easy to use.

    Steripens are pretty awesome conceptually.

    And frankly, from the original classic to the latest and greatest, Steripens all work great.

    I once got sick in Hong Kong many years ago and again in India, and have worried about water ever since.

    In comes Steripen to the rescue.

    Basically, Steripens make living organisms (bacteria, viruses) sterile. As such, you won't kill the bacteria that's in the water, but the ultraviolet light does prevent them from reproducing, so though viruses/bacteria get into your system, the worst that can happen is a little discomfort, and once they die, since they don't reproduce, you're fine.

    Since ultra-violet light as a mechanism is used to treat water at large city water plants, making a handheld version makes sense.

    The concept is simple. A handheld unit, ultraviolet lamp, some basic protection to prevent damage, a rubberized water proof button to start and stop the ultraviolet light (as ultraviolet light is dangerous except when it's immersed in water).

    And for the most part, that core technology hasn't changed much.

    But that first gadget wasn't an ideal fit for everyone. It used disposable CR123 batteries (200 treatments or so) which are expensive, or 4 AA batteries which add to size and both require the need to travel with spares, it was rather largish for a handheld device, and there were hopes to find ways to make the technology safer and simpler. Over time, the gadget has gotten smaller, versions have come out with solar rechargers, 4 regular AA's in some models, or a pair of rechargeable lithium AA's in more compact versions, and new water connector safety mechanisms to prevent the ultraviolet light from lighting up when not immersed in water.

    The size, weight, and USB charging capacity of this purifier would make it great for travel and for shorter backpacking trips (battery only lasts 40 0.5 liter treatments, according to mfr.). However, after literally one use mine began turning on and then turning off before the treatment was completed, or not turning on at all. Reviews I have since read on another site described the same experience. I ended up boiling water for all my water during a three-night hike, when I could have carried only a liter at a time if the Steripen could be relied on, as the trail was all near a water source. I had a similar experience (I should have learned, obviously) with a Steripen Adventurer, which started performing eratically 2 days into a backpack trip in the Sierras 5 yrs. ago. A device used for this purpose has to be 100% reliable, and Steripens are not, in my experience. A shame, but if you can't rely on them, then you have to take alternative purification along (filter, extra fuel, tablets), so the Steripen becomes superfluous. The only use I can see for it with the unreliable operation is to take to someplace like Russia where you could avoid buying some bottled water (or make sure locally bottled water was safe) by using the Steripen, when you could get it to work.

    I go camping quite a bit, but the main reason I bought this unit was for overseas travel where the water supply is not 100% reliable. I have to say after taking this on a recent trip, it worked incredibly well and was very easy to use. The battery lasted the whole two weeks I was abroad and I probably sterilized a few dozen liters of water over the course of that time. I'd happily take this camping with me (though being a safe camper I'd probably want to bring some kind of non-electronic backup like purification tablets or a basic filter).

    I have just a few problems with the unit though; first, the shape of it (and the placement of the water sensor) make it impossible to use with a standard small water bottle like a Sigg or disposable bottle. It seems like the design could be easily made to work with those kinds of bottles, so the fact that it doesn't is a little frustrating. If you plan on using this, you'll have to use wide-mouth bottles. My second problem with the unit is the LED light - it seems like a silly thing to include, though I guess it's always nice to have an emergency backup light. The problem is that the light is activated by moving it in a certain pattern (not with a switch) and so on at least one occasion I found that it turned itself on inside my pack. That's bad for battery life, and could lead to a situation where the purifier isn't able to do its job. Finally, the neoprene case that it comes with left marks on the unit after only minimal use. It's only a cosmetic issue, but it shouldn't happen at all.

    Overall I'd recommend the Steripen to anyone looking to some camping or travelling abroad - the safety and convenience are a great combination.

    I wanted to love this product but it simply would not hold a charge. After reading more about it, that seems to be common with this model. I charged it the day before we left for an 8 night camping trip and on day 2 tried to use it and... nada. Returned it and ordered the adventurer which uses batteries and got amazing reviews for reliability.

    I've had this pen for about 6 months now. This pen can be a flashlight as well. Whats awesome is how the light turns on all by itself and drains the battery life while its in your backpack or pocket. A real Thriller! I love the way when it is charged it seems to be unreliable when its cold outside. I have to bring another filter out with me to make sure I dont get sick. This pen was expensive. Due to the wide position of the UV light sensors, You will also have to make sure you have a large bottle in order to stick your pen into. Any conventional bottles have an opening too small for the PEN. Basically I hate this thing. Im taking it back to the store tomorrow.
