Product Rating Snowed in LIaoShan for five days with all water pipes frozen and all bottled water gone. What was I to do hit the solitary bar for Chinese rice wine or defrost some ice and purify it myself. Only problem is that I needed to melt the ice on a fire, but at least I stayed sober for some of the time. .... I think anyway. -
Product Rating Use has been camping/ tramping and rainwater supply sterilization.
Product is light, well constructed and reliable.
I use the Li ion batteries and would have liked a charge indicator on device to know how full in the wild (use the solar charger). I would like to see a fully waterproof tail cap. -
Product Rating awesome -
Product Rating I used my SteriPen Adventurer on a recent hike of the Inca Trail, in Peru, and it worked great.

Product Rating I can't say enough about the Adventurer Opti. It's quick and easy to use, light weight, and most of all it eliminates the after taste left behind by chlorine and iodine tablets. The UV light removes all doubt of purification and is a great indicator of when your water has been completely purified. -

Zap the germs right out of the water!
Review by Mike the Life Scout from Salisbury Mills, New York USA on 7/19/12Product Rating I got this product because I have a compromised immune system and as a boycsout I was concerned about getting sick from other filtration systems so I called technical support for the specs and then verified the data at my eigth grade science fair project . I tested samples of the local stream water before and after the steri-pen use and it tested my hypothesis for no germ growth in the petri dish for up to two weeks. As a life scout, I felt safe to use this lightweight, portable uv light steri- pen which also has an easy clean-up, compact storage capability and other uses such as a flashlight during my camp trips. I even use it at school and restaurants if I get served tap water. I always know that my drinking water is safe. It fits well over the wide mouth of my Nalgene bottle and has a timer to let me know when it finishes sterilizing my water after a few seconds of swirls. I use the large foldable filter for any large debris which also fits in my pocket. It's an excellent product in all aspects. -
Product Rating I've used on camping trips as well as international travel the last couple of years. All you need is a clear water source and a Nalgene bottle. It's pretty quick and easy to use. The light source broke once but customer service was fast and easy to contact -- very personal too which is unusual these days! My only wish is that it had the round wand of the Classic model so it could fit smaller mouthed bottles but on the other hand, using the Nalgene makes it easy to stir to agitate the water. Highly recommend! -
Product Rating I have used the Steri Pen Adventurer Opti on several trips to India and have remained healthy the entire time. I love the fact that I don't have to purchase bottled water (whose purity in India is sometimes questionable) and dispose of all those plastic bottles. I also love the fact that it is compact and lightweight, as well as reliable. A truly great product! -

Product Rating I love my SteriPEN! I have used it a few times now in the boundry waters and is so nice to have a small lightweight device that I can trust! We actually used one SteriPEN for five people on a 4 day trip. Enough said try to pack water or a bulky device to provide water for 5 people.
This is a must have for families in the event of an Emergency or a planned trip. -
Product Rating I recently spent several days backpacking on The Colorado Trail. My friend had loaned me his Adventurer Opti to use for my trip. Water was in short supply so we had to retrieve water from some pretty mucky places. We also used a Sawyer Filter to compare the two. The SteriPen worked everytime even in some pretty nasty looking water. It was easy to use just fill my wide mouth bottle and push the light for the required amount of time. I was pleased with the light weight, and the fact that it did not need any batteries for the 10 day trip. The only con was that it is hard to filter out the muck in some of the nastier water holes. I have a Classic, and am never sure if it is going to run out of battery life or not. When you are trying to keep your load light the last thing you want is a bag of batteries in your pack. So, it was a pleasure using the Adventure Opti. The only advantage we saw with the Sawyer was that it does not require batteries. Yet, unlike the SteriPen I also am never quit sure if my water is totally clean either. The Adventure Opti is a pleasure to use. It is a lightweight delight to use -vs- the older not so reliable Classic or yet the old pump your water filters. Love the product and would recommend it to any long or short distance hiker for safe and clean water. -
Great for long distance running. Love it
Review by By Grand Canyon Runner from Flagstaff, AZ on 7/15/12Product Rating This Adventurer Opti has been perfect for long distance running in the Grand Canyon. I frequently hike/run 20+ miles and need to get water on the way. The Adventurer Opti has never let me down. I carry spare batteries which are small and light. It also works well when doing day or multi-day unsupported kayak trips where having something small and light is valuable. I have used this traveling in Russia and Mongolia. Great little device.
If there is one drawback, it's having to be patient when I first turn it on. At first it appears to be not working but then the UV light turns on and all is well. -
Product Rating No teste at all.
Good for large quantity of water, and also for just 1 liter on a day trip.
May fail if felt on the ground or other impact, so alwayes take some other small pills for emergancey purify (like some IODINE pills).
The STERI-PEN company provide emazing customer service! -
Product Rating It makes a day in the field easy. No need to pack water. -
Product Rating The principal is wonderful. I use mine to kill virus after I filter the water. The pen will not decontaminate the mouth of the bottle or droplets above the water line. The best way I have found to use the pen alone is to carry a funnel and make sure there are no droplets on the rim or above the water line then all is good. Dipping the water bottle in the water and using the pen is of concern to me since the rim of the bottle will not be decontaminated when your mouth contacts it. I think the premise is that there will not be enough bacteria on this part of the water bottle to cause a problem. My military training was always to spill treated water over the cap and over the mouth of the bottle then let it all decontaminate before I use the water. The pen is great if used correctly. I just mentioned my concern. -
Adventurer Opti is the way to travel!
Review by By Tito the Traveler from San Diego, CA USA on 7/15/12Product Rating I've used the Adventurer while backpacking, fly-fishing and traveling. It's great to know I can drink water wherever I am. The Adventurer is light, easy to use, and gives freedom to travel with little water knowing I can quickly treat while on the go. This is something no backpack should be without!

Product Rating Highly reliabile and effective from wilderness adventures in the Boundary Waters to mission service in Central America. Years of durable service. Trusted.
-
Product Rating I have used this for everything from my backpacking trips, my life in Peace Corps, to my travels in Europe. It is really easy to carry being so small and lightweight and it pretty easy to use.
The downside is that it uses batteries. I don't use the solar charger, but I do have to use the solar charger unit for recharging using the AC adapter for extended trips. I have only ever had a problem with a battery from SteriPen and it was taken care of very promptly! As a company they are extremely good at responding to needs and supporting their products! -
Product Rating Used at every spring on the A.T. No worries. Easy to pack and carry. Always worried about battery life.
I also use it in my kayak on rivers and lakes. Just get some water from the lake run the Steri-Pen through it and drink. -
Product Rating This thing is pretty great. Its small, light weight and quick and easy to use. My only complaint is that the sequence of puishing the button, waiting for the light to flash, then putting it in the water is not really intuitive. I have found myself doing wrong a few times until i figure out the right order. -
Product Rating I originally used the precursor to this the adventurer to through hike the entire Appalachian Trail after research proved that this was more effective and less hassle than a pump. Out of the items I purchased for my hike this was one of about 3 that did not fail the entire 2137 mile 6 month trip in addition to never suffering from any bad water related illnesses. Well designed and thought out thanks so much for a great product.
If that wasn't enough about a year after my hike I had an issue with the on/off button not working. I sent it in and they sent me a brand new one. Absolutely satisfied customer! -
Product Rating I originally bought this product for a solo trip to India six months ago, and though it isn't the intended travel item, it worked very well for me. I also used it while leading a backpacking trip for two weeks and it was perfect. Fast, light, and very handy. It was much faster than our hand pump, and we felt confident using the device over the pump. I have never been sick, and neither have the trip participants, and I would highly recommend the Adventurer Opti, or one of the travel products if you are going international. I would also recommend having the pre filter because I did not, and that would have been really helpful at certain points for me personally. This product works, it's convenient and great to bring on day or multi day hikes. -
Product Rating I got the solar recharger unit package and it works if used per the directions. The Adventurer Opti is easy to use, lightweight and pocket sized, has a nice belt carrier, the lamp cover is very protective adn there seems nothing fragile or poorly designed about the unit. It works quickly and easily each and every time I've tried it. I use this in my camper as I never trust the water in the tank and don't always have bleach to use with it. I use it hiking and have no hestiancy about drinking stream water after using it. It is lighter and smaller and easier to carry on hikes than my Katadyn ceramic filter, and is my preferred gear as I don't take both on day hikes. For a longer hike, I would take the katadyn as a backup though. I really enjoy this and think it is a remarkable and unique product. I'm glad I bought it, and a friend saw mine and immediately ordered the same for himself. -
Product Rating The lake water in Finland is known to be VERY clean. However, it can not always be recommended to drink it, due to seasonal changes in Bacteria and Algae population.
As a guide, I always carry the steripen. This helps me having healthy customers in the remote wilderness areas of Finland= GOOD.
The only minus would be the batteries. However I intend to get the "Freedom" and a USB-Solar charger. -
Product Rating I have the previous generation of the Adventurer. The black and yellow one. Bought it in 2007, and have been using it an average of 10 trips (5-10 uses per trip) every year, some years much higher.
Compared to pumps and chemical treatment, this is by far the easiest to use. Just fill your bottle, dip the Pen, and swirl. On hiking trips, you can be back on the trail in about 2 minutes, with perfectly drinkable water, no messing with hoses and connections for a pump, no waiting for chemical treatment.
The only cons are that you are somewhat limited to which water sources you can use. You need enough depth to submerge your bottle to fill it, or you need some kind of overhang to have water trickle into the bottle. Not really a flaw of the pen, so much as an inherent issue with filling water bottles. Also, you need fairly clear water for the light to work. Bottom line, some limited usability in dry conditions. You can't just stick a hose in a puddle and rely on the filter to filter out the muck. -
Product Rating I've been using this product for a year or so and really like it. It is easy, light, and goes anywhere. I've used it on car camps to backpacking for multiday adventures. I like it a lot! No parts to loose and no pumping! I have found that the replacement batteries are pretty expensive, but as long as you take them out when storing it, they live a longe life. -
Product Rating This is a light weight safe method to treat water in the mountain conditions in Africa. I used this extensively along the east coast of US. -
Product Rating I use my Adventurer Opti for backpacking. Its small size and light weight make it ideal for this purpose, though its short handle makes it difficult to hold onto when wearing gloves and using it with a standard 1-liter nalgene bottle. Its fit-anywhere packability and automatic timing more than make up for this trivial shortcoming however, and the Opti is my primary water sanitization tool, ahead of my cumbersome pump filter, which is now reserved for trips where recent rain has made streams and lakes murky. -
Product Rating My wife and I have been using the Adventurer Opti on treks in the Himalaya Mountains for almost a year now. We use it frequently when we are on the trail between villages and need to refill our water bottles. We have never gotten sick (which is the whole point of the water purifier).
The only con I can think of is that the batteries are expensive, and if you are trying purify water for more than 1 or 2 people, the battery life is not great. Because of this when we are staying in one place for a couple of days we use a pump filter.
This isn't really a con, but you need a wide-mouth water bottle to use this.
This is a GREAT personal water purifier. It comes with a belt pouch so you don't have to dig it out of your day pack when you want to refill your water bottle on the trail. You can't really ask for more in a compact, lightweight, high-quality water purifier. -
Product Rating I ordered this pen to use on one of the toughest hikes - the Na Pali coast on Kauai. It's 11 miles one way. There were multiple streams so we always had a supply of water but the water was questionable because there are wild pigs and goats everywhere - so we used this pen every time we filled up our canteens with stream water. It's so easy to use this pen! The water always tasted good and we were healthy and happy the entire trip! We couldn't have asked for anything more! -
Product Rating I purchased and used this product on a 12 day remote Alaskan hunt. Used it as my sole source of water treatment, and for the entire camp after others ran out of purification tablets.
It is light, small, and can be carried at all times. It works as advertised. However, it takes a long time to use as you should ideally treat water in a quart-sized container, then shake well and treat again to get the water on the inside of the lid and mouth treated as well, as the pen will not treat droplets above the water line. This makes it somewhat slow and tedious to use.
The pen starts VERY slowly in cold weather, and there is no way to be certain it is working during this time, so it takes another treatment or a leap of faith.
Due to the cold, and also having to treat each quart twice, battery life was extremely poor, even with quality lithium CR123's.
In the future I will carry a quality filter for camp/ volume use, and use this as a personal filter only.
By the way, no-one on this trip developed problems from treated water. -
Product Rating <div align="right"><img src="http://trans-americas.com/blog/wp-content/uploads/2012/05/SteriPen.jpg"></div>We're just going to come right out and say it (again): Every responsible traveler should carry a water purification system if they want to be healthy, thrifty and environmentally responsible. That's why we love our SteriPEN. Read our full review : <a href="ttp://trans-americas.com/blog/2012/05/drink-responsibly-steripen/">here</a>.
