User Review: SteriPEN Classic
This is a great water purification device for backpacking- or any other outdoors activity where you want fresh clean drinking water.
First some of the cons... you need enough water that you can totally submerge a nalgene- no pump. This has only been an issue once or twice and someone in my group had a pump- and I had enough water anyways.
Pros- light weight- EASY- FUN- kills everything, even viruses. I like it over filter pump devices because I know it's killing the rare virus, and doesn't have that after taste from pills etc.
Considerations- you can't use alkaline batteries. LET ME REPEAT! You can't use alkaline batteries! You must use rechargeable or NiCad's. I use rechargeable as they are the most reliable.
READ the instructions and don't guess your way through it on the first time and you'll love this thing.
