SteriPEN Ultralight UV Water Purifier

Great unit - nice to feel confident I won't get sick. Esp when combined with the BeFree filter so the water has less contaminants in it before UV blasting. :-)

This has come in very handy in places where water is iffy! Haven’t used it for backpaking yet but it’s very lightweight and should be great for that. Foolproof too and easy to charge.

I was traveling for 3 months around the US and concerned about the water quality in unfamiliar areas. Purchased this filter for travel and will keep at the ready at home for emergency use.

Took this on a Montana hunting trip, worked reasonably well. Then I trusted it on a backcountry Appalachian hunting trip and it failed. I was six + miles in and it was hot and suddenly I had no way to get water because it had lost its (full) charge. So I attached it to my portable charger and it wouldn’t charge. I would not trust this thing for water acquisition. Get a filter like a sawyer.

Very Light, Very Well Designed, Maybe Best on Market

It worked great for 5 months then the charge started getting worse and now it doesn’t even work anymore. No UV light. Red light blinking and green light blinking. Nothing. For 100 dollars this should be working for years not 5 months! Very displeased.

The quality of this pen is terrible, it lit up one time and then would not light again. I would not rely on this product for a filter method at all. It also did not hold a charge.

I went through 2 of these. Neither unit would cycle more than 6-8 times before needing recharging. No where near the 20 cycles advertised. In both cases I got less cycles after a second and third overnight charging. Not something I'm going to rely on in the back country. I went with the (heavier) Traveler model w the CR123 batteries as a replacement.
