For the weight, I believe there is no better backcountry water treatment available. The LifeStraw imparts no strange flavors like its chemical brethren, its flow rate is perfectly acceptable for active pursuits, it has no moving parts to break or filters that need replacing every couple of days, and it does all this at a fraction of the cost and weight of other Filter and UV water treatment options. Besides, what other water treatment system has been tested successfully by people on a daily basis in the most contaminated parts of our planet?

Just got back from a trip to Nepal and Cambodia. I used life straw dozens of times. Most notably while I was in the jungles of Cambodia I found myself dangerously dehydrated and my two water bottles were already empty. There was NO SAFE WATER for me to drink. I did eventually stumble onto a well used by some monks. After figuring out how to prime and pump up the water I used the life straw to drink my fill. I was so relieved, I was miles from the nearest bottle of water and I managed to get my drink on. I didn't have to take a risk that would have put me in an awful situation (severe diarrhea) , and it only cost me $25 and the weight of the straw is negligible.

In fact, I've decided that whenever I'm leaving the country to take this guy with me. Why not?

Tested it in 3 locations
1. Local river --> PASSED
2. Mirror Lake --> PASSED
3. My own Urine -->FAILED

I was curious, I had to try, a little disappointed, that is why I gave it 4 stars.

Bottom Line: Great product if you are a normal person going camping/hiking.

This product is hands-down the best filter out there!

I bought mine at Bass Pro Shops for $19.99, but it happened to be one of the older 3 year shelf life straws, which could explain the price difference(Was manufactured in May).

It takes a second to get the water flowing, and its not easy to "blow out" the water as it recommends, but this thing works great!

My favorite feature is that, when it can't filter water anymore, it just STOPS LETTING YOU SUCK WATER THROUGH IT. Amazing, right? No guesswork...just get a new one ever 3/5 years, and use it till it stops working.

Note: Its a little hard to blow water out, but not impossible. If you find yourself blowing and not getting ANY air out, its cause it sealed itself(however that works) and isn't gonna let any more air pass through, you've gotten enough out already. Don't waste your effort trying to get the last few drops out, it won't happen.

On a 2-day hike, I ran out of water and decided to consume a 1L of fast-flowing (Pennsylvania) river water, filtered through the device. 48 hours later I'm at home and get the grumbles. I was bedridden for 36 hours with it coming out... anywhere it could. Needless to say, this won't filter viruses. You'd better boil or use iodine tabs. I have, however, used the LifeStraw on piped springs in PA with no issue.

Good product but should be improved. The straw is to thick to fit into the neck of standard bottles and canteens. This makes this product totally useless for me. I prefer not having to lie on my stomach in a swamp to drink from a lake while hiking. I would rather fill up my bottle and then use the straw. This can be fixed by including an attachment that can go on the end of the straw and narrow down so it fits in the standard neck. Until then I will go back to my taste altering water purification tablets.

When I was putting together 72-hour bags for our family, I had all the bases covered except for drinking water. I researched for a long time before deciding to get these LifeStraws, but we are very happy with them. They are light-weight (only 2 ounces), made of durable food safe plastic, they filter up to 260 gallons of water, and they allow everyone to have their own source of safe drinking water. They've also been proven effective in preventing water-borne diseases in developing countries for years (nearly a million Lifestraws have been distributed in Kenya). They filter out dangerous pathogens like e-coli, giardia, salmonella and cryptosporidium, and make water from any source safe to drink. They are perfect for survival situations, foreign travel, or even just one-day hiking trips. Time Magazine gave Lifestraw the "Best Invention of the Year" award in 2005.

I bought ours directly EarthEasy.com and not on Amazon, and we've used them several times. They can be used to drink directly from any body of water, but to protect the filter from getting clogged, it's best to pour dirty water through a T-shirt to remove dirt and debris before using the filter.

I like knowing our family won't have to worry about safe drinking water if we're faced with an emergency.

For me this item is worth it's weight in gold as I no longer have to carry any more than a full quart of drinkable canteen water which I now save for emergency only. On a recent 4 day hike/camp excursion I used this straw exclusively for on the go instant hydration if water source was questionable as I camp/hike in New England mostly Maine and a person would have to be a complete idiot not to find nearby water sources no matter where he may be even if he has to tap a tree. As others, just wrap a brown biodegradable coffee filter around the bottom, these filters are cheap 200 for a $ 1.59 will lay flat/light for packing and of course double as a boiled water filter, toilet paper,fire starter, emergency bandages and a dozen other practical uses if needed. I prefer a semi permanent pre filter by using a Coleman or Peerless silk gas lantern mantle slipped over the end and secured with Duct tape.

For those of you concerned about the so called fragile bottom tip/cover and backpack just slip a small plastic pill bottle and tape or rubber walking cane tip over it, no problems.
