Product Description

The smallest, lightest SteriPEN®, the AdventurerOpti Water Purifier uses a revolutionary optical eye to sense the water. The patent-pending technology provides safe use and the standard insulating sleeve around the UV lamp allows purification in even the coldest of waters. Fast, light, easy and effective, the AdventurerOpti provides the ultimate protection from waterborne illnesses. Giardia, cryptosporidium, bacteria and viruses are all destroyed in seconds-by SteriPEN® UV light. The UV lamp provides up to 8,000 one-liter treatments. UV purification works as the ultraviolet energy emitted by the light is absorbed by the cells of the microbe, preventing cell enzymes from 'reading' its DNA. Without intact DNA, microbes can't reproduce to make you sick. The process is simple but effective, destroying over 99.9 percent of harmful microorganisms. Great for camping, hiking and backpacking.Easy to use 1 button operation; LED light quickly indicates when ready to purify, then place the pen like lamp in clear water and stir until indicator light turns green..Dirty water should be pre filtered until clear prior to treatment..The UV lamp provides up to 8,000 one liter treatments..Device works with containers with minimum 1.75 in. diameter opening (ie Nalgene wide-mouth bottles)..Low power indicator lets you know when batteries need replacing..Automatic shut off when treatment is complete..Includes black neoprene case with belt loop and 2 non-rechargeable CR123 batteries and instructions..Size: 15.5cm.

5.0 out of 5 stars This is the Steri-Pen to get September 3, 2010

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.

1.0 out of 5 stars steripen reliability July 13, 2011

By Philip C. Barlin

Color Name:Black|Amazon Verified Purchase

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.

5.0 out of 5 stars Nice update to the classic SteriPen Adventurer May 19, 2010

By Old Scout

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.
