Perfect for dodgy water

I relied upon a UV pen to treat many liters of water on the Inca Trail hike and in my hostel in Cusco, and neither I nor my companions had any GI issues. I have had the same great results in Mexico and on my tour down the Great Divide Mountain Bike Route. And- it makes a nice gift for adventurers, even children, because it’s simple to use: submerge in relatively clear water, press a button, and stir. I carry extra batteries, but have never had to use them on a trip, and the case gives me confidence that it will survive in my pack.

does not function in cool to cold temperatures

I used this item for a 12 day backpacking trip in the Wind River Range in Wyoming in late August - early September. Although it functioned as expected in warm temperatures, it did not work consistently in temperatures in the 40-60ºF range and not at all in lower temperatures. Even if I stored it in my sleeping bag and jacket pockets and pre-warmed the batteries against my body, the device would immediately cool down and cease to function upon use. This renders the pen worthless in most backcountry contexts. Thankfully I had some trusty AquaMira as a backup, and I resigned to using that most hours of the day.

7 days and NO intestinal issues!

I took this on my recent elk hunt and pulled water continually from streams all week long. NO issues with the squirts or sickness so I feel the pen worked perfectly. No issues with the batteries, size or durability at all!

Bad quality control, not reliable

Familiarity:
I've used it several times

I've tried it in water bottles, nalgenes and even cups. The light will turn on for about 10 seconds then turn off, then I'll get a picture of a light bulb and a frowny face. Apparently the bulb is dead or been damaged right out of the box. Probably stick to a filter or tablets after this. Ended up having to drink snowmelt, lesson learned

Easy and compact. Saves me from carrying water weight the bike.

this is my backup water system

Great backup system that is small and charges off usb Always keep it on hand if our filter fails.

long life and very reliable even in desert streams which will clog up many filters. Just don't let it submerge or it ruins the electronics

More confidence

I gave this 5 stars because when paired with the backpacker water filter I know the water my family and I are drinking is safe. I have used it backpacking and hunting all over Alaska and have never had any issues.

The only reason this is not getting 5 stars is because compared to the BeFree filter there is an extra step of work here.
