    Very poor product that needs a lot of work in our experience. We ordered two, one arrived DOA and the other only works intermittently.

    bought this as an experiment- first attempt with new alkaline batteries went well- then stepped back to using some slightly older batteries and the UV light went on but off quickly- it appears that complaints about the performance are related to a set of batteries that are overall weak or mis-matched weak ones with a couple of strong ones. So, the verdict is that this is a good system provided you have a strong set of 4 AA batteries. I will keep a set of strong new Li batteries for my prepper needs. The 4 star rating will be up graded when i complete the experiments with my Ni/NiH rechargables- I like the compact structure of the unit and it appears to be sturdy.

    Great, light-weight water purifier. Awaiting opportunity to test in the field. Not sure how it will do with muddy, stagnant desert water. But will try at first opportunity. It packs nice and the only weigh really is the batteries in the unit. I am excited to have this and work with it this spring & summer... I plan to report back my findings.... more to be revealed.

    Been using a Steripen for 8 years now - used it for multi-day hikes trekking thru Asia and South America. Also used it for treating hotel tap water in Mexico, Cuba, Bhutan, Nepal, Peru - never, ever had any problems. Their is a little trick to using it as I have seen some users have difficultly using it - you have to wait a second or two as the green light blinks AND THEN put in the water bottle. If you press the button and put it straight in the water bottle, light turns red and is not ready to use. Be patient - I highly recommend this device for all your travels.

    Great when it works, frustrating when it doesn't. I have an older SteriPen I use for travel. It is very finicky about the salinity of the water -- a little too conductive, or not conductive enough, and there you are, using Iodine again. I bought a new one, hoping this had been fixed. It worked once, and the lamp failed. Sierra replaced, and the replacement seems to work with local water -- We'll see how it does on varying water on future trips. Always take chemical back-up.

  • “Does the SteriPen Classic water purifier include a prefilter?”
    Asked by The Tagueteam from Indiana on 8/3/2015 11:52:27 AM
    • No prefilter is included. If you are purifying cloudy/muddy water, the instructions suggest it may not be sufficient to only use the pen. However, I've used it on tap water in South America, and would use it in running streams here in the US without hesitation.

    • no, the steripen is just a device that you insert/dip in a bottle/glass of water and after about a minute kills all bacteria viruses and protozoa. You would need to get a lifestraw or similar to strain out the water, but those types of filters rarely protect against viruses/bacteria

  • “How do you use it ”
    Asked by Bill from SC on 7/15/2015 2:39:41 PM
    • Using the SteriPEN is really simple. I filled a 750ml Nalgene bottle with tap water in Peru. Insert the SteriPEN and press the button (which will treat 1 liter). Swirl around the SteriPEN, stirring the water a bit until the light turns off. That's it, you're done.

      Be sure to either 1) prevent untreated water from contacting the lid or rim of the bottle, or 2) lightly connect the lid and let treated water drizzle out to rinse any potential contaminated water.
