Reliable And Convenient
After using this on multiple backpacking and hunting trips in 2025, I believe. This purifier is so convenient compared to pump or gravity filters, it is worth the extra weight and batteries. I took three of my kids (under 12 year old) on a backpacking trip, and this saved me so much time and effort. It is easy to teach others how to use, so once I train my children, this will be an easy way for them to help. I appreciate the reliability of this purifier. I used this even after night temperatures dropped below freezing and did not have to worry about it freezing, unlike my backup micron filter (I kept that in my sleeping bag). Overall, this purifier is very convenient and reliable. The draw backs are the size and weight, which makes it less attractive for ultralight systems.

Battery Door Does Not Close
Great find for a quick trip to South America. The battery door does not close well and therefore extra care is needed when using the device for water treatment. I would not recommend trying to manage the door, the batteries, and a water bottle in places where batteries could be lost/dropped.

Clean Water
Wasn’t working great when I first started using it maybe it was the battery or how cold it was because we were up sheep hunting and malfunctioned a few times.

Great Little Back Up For Back-packing
I really like this Steripen, the ability to use fresh batteries makes it easier to swap out power source, instead of relying on an internal rechargeable battery.

Great For Emergency Pack
These steripens take up very little space in my emergency packs and are worth their weight in gold in an emergency. They are foolproof to use and get you safe drinking water in 90 seconds.
