5.0 out of 5 stars This is a Game Changer```` April 5, 2012

By Susan Miller

Being an avid backpacker for years my biggest issues come from weight. I like to go ultralight due to back injuries I suffered in High School. The difference of 8 pounds can be the difference between a fun trip and one of incredible pain (and one I will feel for days)! My pack usually comes in under 20lbs and this includes tent, pack, sleeping bag, sleeping pad, food, stove, pillow, rain jacket, rain pants, a change of socks, tent footprint and some other odds and ins. This lacks water! In the past I've carried a 3liter water bladder and as you can imagine, that's a lot of weight. Each liter weighs 2.2lbs so a 3 liter bag is almost 7lbs of additional weight! For me that's too much.

Previously I would use tablets and drops to sterilize my water but not anymore! A friend of mine recommend this to me and it really has changed my entire system (backpacking). I'm able to carry the Steripen Adventurer UV and a quart water container and refill and sterilize as I go. Simply amazing! The differences between a quart of water and 3liters is HUGE!

So to the 'Pen.' It's amazing! Lightweight, quick to use and a very high quality product. I love the recharging ability of the solar container. I hook it to my pack and it charges as I go. You simply can't get any better than this or any smarter! I live in the mountains of NC so water is always close by so I don't have to worry about infrequent sources. This allows me to carry less, quickly sterilize and continue on.

One of the best purchases I have ever made!

UPDATE: I have nothing but great things to say about this device. It is absolutely amazing to say the least. I recently used it on a 2 day, 30 mile back packing adventure where I used it to filter roughly 4 liters of water from a drainage ditch!!! Strain it, purify, then drink. No issues what so ever! I have yet to use the charger other than the first time. Normally I leave it at home and take along an extra set of batteries to save on weight.

Size is bigger than expected. Use this in water filtered by charcoal/ceramic filter for double protection. No stomach ache and nothing. Water taste good from the tap and river.

1.0 out of 5 stars Not what's pictured March 14, 2012

By J. Mackey

Color Name:Black with Green Accents| Size Name:One Size|Amazon Verified Purchase

First off, let me start by saying the product itself is *awesome* and worthy of at least 4 stars. It functions as advertised, and seems much more reliable (thus far) than previous models. My gripe and reason for the low rating is with what's pictured as the advertisement. What you see in the picture is NOT what you actually get in the package. The solar charger for this model was *THE DECIDING FACTOR* for this particular unit for me, since I figured I could strap it to the top of my pack and have it recharge on the fly. Even with the single battery many others mentioned, I figured the ability to charge it when not being used would be a fair compromise, and the product information mentions it could treat up to 50 liters of water on a single charge. Of note, CR123 batteries are odd-sized, like stubby AAs from cameras. I was hoping this product would use a common sized battery, but couldn't find anything definitive since the picture showed what appeared to be a single, rechargeable AA.

What you actually get in the package, however, is just the unit itself and the neoprene sleeve--the two center items in the second photo of the product page. It comes with two *disposable* CR123 batteries. Let me say that another way--the batteries shipped with this unit are NOT rechargeable, and you don't get the recharger nor the AC adapter for it. I'd consider that false advertisement, since two of the three photos on the product page show the unit with a solar recharger. I could have purchased the same unit as-is locally on sale for $50.00, but passed it up for the one as advertised on Amazon since I thought I'd be getting more value for my money. If I didn't actually need to use the unit this weekend, it would be on it's way back.

UPDATE: I contacted Amazon customer service about the above issue, and they went out of their way to make it right. They overnighted a replacement, saying perhaps the order got mixed up with a different bundle, but also saying I *might* get the same thing again since the part numbers and descriptions come from the manufacturer. Indeed, it was exactly the same thing as what was I described above, so I'll take it up with Steripen. In the meantime, Amazon said they'd update the catalog entry to reflect what's actually being shipped.
