    SteriPEN Ultra Water Purifier is rated 4.0 out of 5 by 13.
    Rated 4 out of 5 by from Works This is the first UV purifier I've used having used various pump-type filters for many years before this. It's much easier to use (smaller and lighter too) than any filter; however, one thing to keep in mind - it doesn't address any residual water on the threads of your water bottle (assuming it was filled by dipping into your water source). So, be careful to also rinse the thread/cap with purified water after treatment. The purifier seems well built and well thought out though it is affected by the cold and the screen is a little hard to read in the direct sun, as you would expect. As others have noted, ice cold water will slow the purification process down, but not by too much. The other thing to be aware of, the battery will be negatively affected (like they all are) by cold temps. So, don't leave it out on very cold nights because it may not work right away in the morning (perns. experience; once I warmed it up, it worked fine). The thing is very easy and pretty fool proof to use (press the button and watch the countdown indicator). I've used it in temps. ranging from below freezing to really warm. I have not had it long enough to comment on its durability nor its advertised "50 cycles" of uses per charge. My water sources too, so far (three multi-day backpacking trips), have been clear Sierra Nevada streams and lakes (I carry backup purification tablets too, just in case; you never know).

    Rated 5 out of 5 by from USE THIS FOR TRAVEL TO ASIA!! I used the Steri-pen EVERY DAY for a month in Nepal in July 2013. In Nepal, even bottled water is not safe to drink (as indicated by the WHO). I filtered through the 40 Micron Fits-All filter, first, then twist that filter out and put the Steri-pen in and shake gently for 90 seconds until smiley face pops up. The USB charge lasted the entire month! Also, since I home-stayed with poor families who normally have to boil water for their boarders, the Steri-pen eliminated the need for using costly cooking fuel.

    Rated 5 out of 5 by from Takes the guesswork out! I've used this product on a couple of different occasions and it has been a wonder each time! The water sensors are easier to keep in the water than the previous steripen editions I've used. The interface is easy to read in direct sunlight and makes the process very user friendly. There is no guess work with this product, it has a countdown timer on it that lets you know how much longer you have until it is finished. The smiley face at the end is cute, but the other things it shows you at the end is more useful. It shows you the (rechargeable) battery strength and the approximate condition that the bulb is in. I've used this on multiple long day trips so I don't have to carry a lot of water with me. I've only used it on 1 overnight but this thing has yet to show me a hiccup. I charged the battery when I got it a couple of months ago and it hasn't budged yet, even with heavy use on the extended day trips. Having a rechargeable battery in the thing is very nice. Having it be recharged by USB is even better, I can recharge it off my solar charger if I had to.

    Rated 4 out of 5 by from Light and Easy Lighter and smaller than my pump filter and no chemical taste added to water. Get the pre-filter to help get particulates out. I've used it in Idaho's high mountain lakes and creeks which are clean to begin with. If your water source is going to be muddy, use a tradition pump filter.

    Rated 4 out of 5 by from Excellent use in the backcountry I just completed the John Muir Trail using this as my sole water purification method. I had bleach as a backup, but didn't have to use it. The Steripen worked flawlessly for me every time, and left me confident that my water was pure. The only issue I had was one time when the battery indicator showed a half charge, but when I inserted the pen in the water, it flashed a frown face and showed inadequate battery level. Fortunately I had a solar battery charger and was able to recharge the battery and continue using the pen. After that I made sure to recharge the battery whenever the charge indicator went below 3/4. I had to buy a Nalgene bottle that had a mouth wide enough to fit. The bottle had to be quite full for the pen to reach deep enough. Otherwise it was convenient and simple to use.

    Rated 4 out of 5 by from Easy to use and fast I recently bought the Steripen Ultra for a multi-day backpacking trip in the Adirondacks. I love that it is lightweight, small and fast. I especially liked being able to fill bottles at the river and then bring them back to the campsite to purify the water instead of having to do it at the source. I put some pantyhose over a small 1L soft bottle for filtering purposes then poured the water into a wide mouth Nalgene to purify and it worked great! The steripen let me know right away if I didn't have the pen far enough into the water and I got the frowny face.

    Rated 5 out of 5 by from Great product The Steripen works great. just used it for the first time on a trip with lots of water crossings. I kept it on my belt the entire way stopping and getting clean water as needed. It allowed me to carry less water at a time, and without getting out the tubes and hassle of a normal water pump, I could fill the bottle up as I passed by a creek and purify as I walked. Just make sure the mouth of your water bottle allows for the size of the pen plus a little more for stering. All the doubt of the item went out the door once I used it.

    Rated 4 out of 5 by from Works Great! This product works great. So far I've used it overseas to purify tap water and for a four day backpacking trip in Yosemite. I have never been sick from using it so far. The positives are that it's compact and quick to use and dry. You can even use it while you're hiking. The only downside is that without the filter there are some little floaties if you're filling up from a stream.
