Hydro Photon SteriPEN Classic Handheld Water Purifier

"User Friendly There is really no thinking involved with this product. It is the most user friendly device I have ever used. Just make sure you have charged batteries before the trip, get some water, push a button and stir to sterilize. There is a light that lets you know when it is sterile. It can't get any easier. It is a little heavy but there is no sour after taste like there is with sterilizing tablets. "

" Convenient I've used this for camping trips but also took it to India. It's very portable and it was reassuring to have something in my bag at all times that is effective, incredibly easy to use, and leaves no after-taste. I used it every day for over 2 weeks and did not need to change the batteries."

" EASY PURIFYING It may be hard to believe that stirring a UV light in some water will purify it and there really is no signs that it is doing its job but I must say that while i have used this pen i have never had an health issues from drinking water treated with this pen. It is very easy to use, light, compact and doesn't effect the taste of the water. I did however have an issue with it when it refused start. Instructions suggested drying it out and an hour or so in the sun seemed to fix the problem that never returned. You can also buy a filter/steripen bracket that screws into the top of a nalgene bottle that is very handy in water that has 'bits' in it."

" security blanket I used a different model called the Adventurer which I bought here and used it for a month in Tanzania. I experienced no quick weight loss programs or visits to foreign medical facilities. It was a comfort knowing that it is thorough and close to being 100% foolproof, it is also very quick and convenient. I recommend it for use on any clear water source (not recommended for cloudy water without pre-filtering.)"
