I continue to be very pleased with my SteriPen.
Bold Consumer
If possible, and I imagine it may not be in an emergency situation, it's probably a good idea to run the water through a filter as well.
Ashley S
The battery cap must be aligned properly for the device to work but it will seal in other positions to prevent accidental activation.

Color Name: RedSize Name: One Size
Short review:

No method of water treatment is perfect for every situation but for people who will be drinking relatively clean and colorless municipal, well, spring, or bottled water that merely requires disinfection to render microorganisms harmless, the SteriPEN is ideal.

Long Review:

The Emergency is the basic SteriPEN model with a red color scheme. All of the SteriPENs have the same basic mechanism with differences being in form, weight, type of battery, and expected battery life. Some of the models also have LCD readouts. They are sold in different colors and with or without batteries, a storage pouch, filters, etc. The primary difference is between the heavier ones that use four AA batteries and the ones that use two CR123 batteries. The Emergency uses AA batteries and fits tightly into water bottles for inversion and agitation.

The SteriPEN website provides charts that compare some of the models to each other, a very extensive FAQ, and user manuals. It is well worth spending some time there before choosing a particular model.

Ultraviolet or UV radiation is invisible but the lamp on the SteriPEN also emits energy in the visible spectrum which appears as bluish light. UV must penetrate the water and reach the microorganism and then go through the cell membrane and body to disrupt the DNA molecules and prevent reproduction. UV does not remove the microorganisms or any particulate matter in the water and it does not affect the way water tastes or smells. UV radiation has only been used in the U.S. to disinfect water since 1916 but sunlight was known to disinfect water in ancient Greece and India and UV is now commonly used in municipal water purification plants.

Color Name: RedSize Name: One Size Vine Customer Review of Free Product ( What's this? )
Reviewer Note: Below I am providing my review of the SteriPEN Traveler Handheld UV Water Purifier because, after using both of these products for several weeks, I have come to the conclusion that they are the EXACT same except for different coloring. SteriPEN's marketing department seems to be trying to brand their pens differently to attract more customers. I don't necessarily fault them for that, but it is confusing.

Original review for the SteriPEN Traveler, same as the SteriPEN Emergency:

SteriPEN is a portable water purification device that uses UV light to purify water found in untreated sources (mainly rivers and lakes) into a drinkable state, killing over 99.9 percent of harmful microorganisms that can lead to illness. This is mainly a concern for people in developing countries and campers/backpackers. As a longtime backpacker, I've dealt with water purification for many years. The most realistic options currently available to me are:

1. Potable water - For the longest time, I just brought in all the drinkable water I would need for a trip and carried it with me. Once I realized how foolish it was to carry the weight of 2-3 gallons worth of water with me in my pack as opposed to 2 liters, I quickly stopped this practice.
2. Boiling - Without a doubt, the best way to purify water is to boil it for three minutes. Of course the problem you run into is that you need a source of heat for this. I don't like wasting my fuel on boiling water when I need it for cooking. And if you are a minimalist backpacker, you don't want to have to lug a cooking system with you just to purify water.

Color Name: RedSize Name: One Size Vine Customer Review of Free Product ( What's this? )
Living in Hurricane Central (for the US, that is), I'm no stranger to boil-water orders and power outages, nor to vast, barren shelves at the supermarket that formerly held bottles of water. The SteriPEN is a nice alternative to having to stock up on perishable water or keep less handy purification systems in the house. It takes up almost no space, it has no expiration date, and it can handle as much water as one's stock of regular AA batteries will allow. The requirement for lithium or rechargeable batteries is annoying, but the included instructions make that very clear (and even include coupons for them). Of course, rechargeable batteries aren't much of an option when hiking or when the power is out after a storm.

The unit itself feels quite sturdy, although with batteries loaded it might be annoyingly heavy for hiking. (I'm not a hiker, so I can't say for sure. It weighs about one pound without batteries.) The one other attribute that's less than ideal is the 2-LED feedback system. The instructions include a chart with no less than 13 different combinations of steady, blinking, and flashing signals to identify the status of the unit. As with the weight, this is less of an issue for home use than it is for hikers who will have one more small thing to keep track of (unless one memorizes all the codes).

It's probably more expensive than a stock of bottled water, but it's a whole lot more convenient.

Color Name: RedSize Name: One Size Verified Purchase
Thankfully I tested this before I needed it.
It simply was not functional. I am not sure if there is any QC on the factory for these things, but there should be. And it should have indicated this was a dud.
I understand the theory of UV sterilization quite well, in fact- a soda bottle on a rooftop will achieve the same results with several hours exposure, but a pocket solution that can work at night is a plus (if it worked.)
Now understand that I did reorder and got a working one, but that is something now that I have a real hard time trusting will be there for me when I need it.
So - my suggestion: Keep an alternative method to sanitize water handy. Keep some Iodine, etc. And use them in conjunction with a filter, even a cheap brita pitcher will remove debris and the larger bugs that are resistant to sterilization. But about this device- I love the fact it uses AA batteries (everyone has them, AA-Lithiums store "forever" and are available everywhere, rechargies are CHEAP and solar charging is easily achieved. It makes good sense to use AA's for ANYTHING vital.) - If only it worked more than a quick flash.
(the indication was that the bulb was "bad")
It's replacement (the working one) is sitting in the e-kit alongside a small bit of "pool shock / Sodium Hypochlorite" for making impromptu bleach, and a bottle of iodine tabs. (the shock is a last resort, but it does NOT expire!) And a mini carbon filter will remove the "blah"... So I do not fully trust this device now... Heed that! But I prefer it over chemicals- as long as it works.
