This has been mostly used for a trip to Nepal, it was a pleasure to use, and I imagine the main factor in keeping my completely healthy for 6 weeks.
I used it everyday for almost all of my water and I changed the batteries once. A great little thing if mineral water is hard to come by, its helped me out many a time when I have needed just a little water to brush my teeth, but cant be bothered to go out and find a shop!
Alternatives to this (things that kill viruses as well bacteria) are not terribly convincing, this is completely chemical free, and my tongue and general well being appreciate that.
I used it after filtering the water beforehand with a homemade gravity filter, as the water must be fairly clear to remain effective.
The only thing I would like to see improved is the strength of the led light which indicates the UV bulb is on; It can be a little difficult to see in direct sunlight, it is possible though, you may need to use your body to create a shadow. So not a massive issue!

Bought this item before going for a survival adventures to west America states.
It's very easy to use, just need to make sure that gloving pen is all time in the water while gloving- some steering movements may cause it to stop water treating process. I do believe that this water purifier kills most of harmful bacteria in the water, but you never can be sure and you are in situation that you have to relay on it. And water has to be very clean to do this process! If you're on the move and you get some clean water to collect in a jar, you can use it surely it will work, but if you can boil water I would recommend to boil the water and you'll be sure that it's definitely purified. BUT DON'T FORGET THAT IN BOTH WAYS YOU STILL NEED TO FILTER WATER, BEFORE DRINKING IT

This is the Steri-Pen to get

I had the old model Adventurer that frequently turned itself off in the middle of a purification cycle or wouldn't start at all. This model fixes all those problems, plus it works as a backup flashlight. It's been absolutely reliable on four trips now and I love it. Sure beats carrying a 1 lb. filter.
I recommend you get a water-clear bottle so it's easy to see when the UV light turns off; Nalgene makes one in the Tritan series. Tinted bottles make it hard to see whether the light is glowing or not, especially in the sun.

steripen reliability

Recently I completed the Kokoda track walk in Papua and New Guinea. Once on this walk there is no support so your gear has to be reliable and effective. In preparation I had acquired this model of steripen through Amazon. When it arrived I tested it and found the internal connections around the battery were not good, however, a small piece of aluminium foil seemed to complete the circuit consistently. [ideally I would have returned the item to Amazon for replacement but the logistics of sending it back from Australia and then waiting for the new one were not possible in the time before I left - this is no criticism of Amazon's despatch and delivery time which has always been excellent]. On day 3 of the 8 day walk the pen stopped working and would not resume no matter how much fiddling I did with some more aluminium foil. Fortunately I had taken purification pills just in case and they came in handy.
In the party was another person who had an identical steripen [coincidentally acquired from Amazon too] that also failed. So in all two of twenty pens failed.
Fortunately neither party became ill largely through disciplined personal hygiene, the use of our back up procedures and guides taking us to streams that they believed were clean.
I know many have used steripens without an issue but frankly this concerned me because when it was really needed this product did not prove electrically reliable. If you do buy one I STRONGLY recommend you test test test it when you receive it rather than finding out in the field that you bought a lemon.

Nice update to the classic SteriPen Adventurer

I had held off on getting one of these for awhile. Basically the concept seemed like magic to me. Wave the magic light in your water and kill all the germs. Well guess what? They work.
You will still need to filter to get any chunks out, SteriPen makes the FitsAll Filter just for this purpose. The FitsAll filter also acts like and adapter to fit the SteriPEN into a Kleen Kanteen. That makes for 1 liter of water purified in less than a minute.
This model comes with a nice neoprene case that will clip to your belt and a removable hard plastic cover that helps protect the end. It also has a flash light function, so you can filter at night.
They have also put in some circuitry to keep it from turning on unless you have it submerged in the water. So no more accidentally turning it on and running down the batter. I haven't had this model for too long, but I'm loving it so far.
