User Review: SteriPEN Classic
Price Paid: $89
Drank from sources I would classify as "questionable" and never had "a bad experience". This has been a companion of mine not only on overnight trips but also on day hikes and remote mountain bike excursions, so I don't have to carry as much water up the hill.
The prefilter is a good investment, as using a bandana to filter out sediments can be frustrating. I was skeptical at first that the little light was going to do the job but now I am a believer. Small, light, no pumping, must have!!
