Awesome for Peace Corps in Guam!

Familiarity:
I've used it several times
Fit:
True to size

This pen appears to have it all - lightest steripen ever, most compact, best price, and it touts great performance specs. What a deal - all those people buying the larger, heavier, more expensive pens are total shills, right? Nope. While this pen IS light and compact, it's compact size is its downfall. With such a small battery located so near the (cold) water its treating, this pen is VERY susceptible to premature battery drain from the cold. I bought this for two uses - treating stream/spring water on long runs in the Wasatch range, and treating water on October overnight backcountry elk hunts in the Uintas. In both places, the available water is chilly - so chilly that it kills the (fully charged that morning) battery in fewer than ten liters! Mind you, this is with an essentially new device, which has fewer than ten charge cycles on the battery with a high-quality charger. The only way I've found to maintain battery functionality is to re-warm the pen at skin level for a few minutes between bottles and the hike with it in an inside pocket and sleep with it. I'll keep this as a fast, light option for trail runs, but it'll be staying at home for any future overnight trips north of the Tropic of Cancer. Yikes.

Low battery light comes on after one use

Familiarity:
I've used it several times

I have charged this three times and only once did the low battery light not come on. I have had the original steripen for a few years and used it for international travel and backcountry use. I gave it up because it was unreliable. I changed the battery and the light and it still could not be relied on to work. I heard this new one was super reliable and was jazzed to get it and use it. It is an excellent option for water purification but only if it is reliable. Now I have to bring an extra backup or use tablets. Grrrr. Why can't they get this right. Water purification in the backcountry is absolutely essential. Hopefully they will replace this.

Low battery indicator turns on too soon

Familiarity:
I've used it once or twice and have initial impressions

Seems to work as advertised, with about 21-22 treatments per charge. However, the low battery indicator (alternating green and red LEDs) turned on after only about 7 treatments from a full battery. On my first try, after fully charging out of the box, the low battery indicator came on after only one treatment. Steripen customer service was polite but did not provide any insight. I'll take it on a 5 day trip in a few weeks and see if I can live with the early low battery indicator---looks like a design or manufacturing issue to me.
