I mostly use it for cycle touring. I fill up my water bottles at petrol stations, churches etc. Put the uv in and a couple of minutes later it is ready to drink. It is important to splash the neck in/out and lid of the water bottle to rinse any untreated water away. Take spare batteries, they are expensive and hard to find. Remove the batteries when stored for a while, as they will drain. I put a piece of plastic between the battery and lid/contact. Hard to see if it is on when outside on a bright day. Also used for canoe touring. For fast and light hiking in Snowdonia, I took the uv and a cup. Drinking from streams as I went. No heavy water bottle. Tablets as a backup.

Does what it says on the tin, easy to use and fit my CR123a/16340 batteries that I have for torches...
Will bring it on all foreign holidays aswell as making it part of my day hiking pack.
Easy to use and works well with my Nalgene 32oz wide mouth bottle.

5.0 out of 5 stars Save $$ on bottled/boiled water 1 May 2015
By Timothy McFadden - Published on Amazon.com
Verified Purchase
This was the absolute BEST thing we purchased for our recent Everest Base Camp trek. It worked like a charm, and we used it multiple times per day. We never had to purchase bottled/boiled water. Another great thing (depending on where you are at) is that the SteriPEN doesn't change the taste of the water. That was great up in the Himalaya (Kathmandu was a different story).

I really wanted to get the USB rechargeable SteriPEN. Although it would have been perfect for camping, it was going to be a pain on our trek. That's why we purchased this version. We went through 2 sets of batteries and we were on our 3rd. It functioned perfectly; we never had an issue.

This also works VERY fast as opposed to iodine/chlorine tablets. Those can take up to 4 hours to kill cryptosporidia/giardia. The SteriPEN "kills" everything in 90 seconds. Granted, that's "per liter", but it's still a lot quicker.

The only downside I can think of is "one liter at a time". It worked great for 2 people. I would certainly look for some kind of gravity device for large groups (not to mention you "only" get ~50 liters on new batteries).

EDIT: 3/29/2016

I've had this pen for almost a year now (can't believe it's been that long since I was in Nepal). It's still holding up to a 5 star review. We've since taken on a couple of trips (one time to Mexico and one time to Guatemala).

After reading some of the other reviews, I feel like I should mention that this works best with 1 liter, wide-mouth bottles. I actually purchased a Camelbak Chute (CamelBak Chute Water Bottle, Bluegrass, 1-Liter) to go along with this particular SteriPEN (and I needed a new water bottle anyway). You can treat less than 1 liter, but you should never treat more than 1 liter at a time (and no ice). For example, you could treat a glass of tap water (as long as it's deep enough to make contact with the contacts).

The SteriPEN never reached the bottom of the Chute. However, there was enough room to agitate the contaminated water by sticking the pen down in and then swirling it around. All I can say is that neither my wife nor I ever got sick using this system.

5.0 out of 5 stars Keeping healthy with ease. Steri PEN is a great invention. 3 Jun. 2015
By J. Safian - Published on Amazon.com

this is my 2nd steriPEN--my original worked so well for my trip to Myranmar in March. So easy and I never got sick. I saved a lot of money too. I purchased this one for my niece who is quite a traveller too. She is so excited about it. It lives up to its reputation and so easy to use. Would recommend bringing a loud mouth container to hold the water as the steripen needs room to circulate, won't fit in a small mouth container.

5.0 out of 5 stars Great reliable product 14 Jan. 2017
By Amy Willman - Published on Amazon.com

The little gadget is a great addition to any hiking or outdoor trip, or trip to somewhere that your uncertain of water quality. We recently went to Bocas del Toro, Panama for 2 weeks. Most places in the area purify rain catchment water and it's drinkable. However, the last place we stayed at the shower water in our bungalow didn't have drinkable water so we used the Steripen when we filled our Nalgene water bottle and it worked great. I perform microbiological testing at a company and took the Steripen to work before my trip to do a little test. I performed Total plate count testing on a tap water sample and on the same tap water sample that I used the Steripen on. the tap sample had low TPC counts to start with (12 cfu/g), but the sample that I used the Steripen on had 0. It was a basic test and only one rep, but it was a little bit of my own data that made me feel a little more confident about using this item. It's compact and has a nice little case to travel with and super easy to use.

Used it on my recent trip to Fiji. I have a sensitive stomach and anything affects me. I didn't want to take that chance, so I bought this sterilizer for water. It must have worked well because I didn't get sick!
