After buying Steripen, I still boiled my water for awhile, but now have total confidence in this product. Couldn't be easier to use. Now I'm saving lots of stove fuel and drinking healthy water. The prefilter is a MUST in combination with the Steripen. Clear, clean water.

I used this product on a hike of the Long Trail in Vermont last fall with the SteriPEN Journey LCD Ultraviolet Water UV Purifier. If you end up having to drink water from a murky source, then this product will do a great job of keeping the sediment out. If the Steripen is your solution to water purification, then I would definitely recommend bringing the prefilter along - it will definitely increase the quality/taste of the water you end up drinking.

I love how it works and I really trust it to work every time. Can't say much more about it since it is so simple. My only advice is to try one on your bottle first. Mine fit nalgenes like a glove, but on my camelback, it is really tight. Still works fine, but a little harder to use. I keep mine in a ziplock when I'm on the trail, not on the bottle. You can leave it on, you just have to try a few different ways.
Also, when it is dry, it does not work! You have to wet it and it will flow very fast. It will stay wet on the trail after the first use. Not a flaw, it is just a very fine mesh in the filter.

It arrived in a timely manner as expected. What more can I say it is a prefilter it does as it states keeps the sediments out. Works fine.

Do not buy one.

The Steripen is dead weight on a backpacking trip. I used it successfully for 3 days, and the lamp stopped working. I returned it, which was supposed to take 2-3 days, and it was gone for 2 weeks. When I received it, it worked at home, but on the first day of my next trip, it only purified 3 quarts, with brand new lithium batteries, (which they recommend), before failing. I tried 5 or 6 times to get it to work, following the manual, with no luck. I then replaced the batteries with fully charged NiMH batteries. It purified one quart, and failed again. I tried with brand new duracells, with no luck.

Luckily I carry iodine tablets as a backup. Without them I would have been out of luck.

I spend 25-30 days a year backpacking. My old filter is a far more reliable and quicker way to purify water in the back country.
