This system is much like everyone mentions. It's light, weighing about as much as 5 quarters. It's compact, about the size of a roll of pennies. The filtration unit seems pretty sturdy and would probably not crack if dropped. The straw seems OK, about the same quality as the flexi-straws you get with $10 plastic water bottles. I'd worry that the straw might crack with repeated use, but it should be fine if you use it only for emergency purposes (i.e. rarely).

As with all carbon-based filters, this one has a lot of dust when you first use it. I forgot this detail and was surprised by the straw full of coffee-colored water on my first draw. There is a note on the unit that warns about this dust (which I didn't notice until later). The note implies that all of the dust would disappear after the first draw. That is not true. I've drawn about 4 cups of water through the system, yet there is still very noticeable dust in the water. It's no longer the color of coffee, more like weak tea. I'm OK with this, but my wife and daughter would complain (of course, they probably wouldn't complain too long if there's no other water).

In sum, I think this is a good product and recommend it for emergency use. But I suggest drawing a few cups of water to remove the carbon before you store it in your emergency kit.

I bought the Aquamira filtration straw as a lightweight way to keep safe and not get sick from water-born illnesses (Cryptosporidiosis and Giardiasis being the two major ones) while abroad. I still carry water filtration tablets while abroad as a "just in case" item, but let's face it - that's a pain to deal with and you need to be planning ahead. Sometimes you just need to drink now.

I really can't get over how light this thing is. It weighs less than an ounce, and fits easily inside of any pocket you can think of. The collapsible straw is a bonus. The straw is rated at being able to filter around 20 gallons of water before it's discarded.

The price and size make this a "must have" for any hiker/camper/traveler/survivalist. Sure, you'll probably not use it, you'll be glad you have it.

This thing is great. You can drink from a mud puddle and it still taste clean. One time I was camping and it started raining so I threw up the poncho and put my metal cup out to collect water. Well pigment from the poncho came off since it hadn't been used before, as well as smoke that had collected. I tasted the water pre filter and it was foul, undrinkable. but with the filter it was clean and cold. My friend tried the filter and said yeah taste like water, then I had him taste the unfiltered stuff and he just about puked lol

This will remove the vast majority of cysts like giardia and cryptosporidia, but it will not remove enough, if any, bacteria or viruses. If used as the manufacturer recommends, in conjunction with water purification chemicals, it can be a good system since the chemicals take hours to kill cysts but only minutes to kill bacteria and viruses, while the filter can remove the cysts immediately, as well as any chemical flavors via the charcoal. IT WOULD BE DANGEROUS IF USED ALONE IN THIRD WORLD COUNTRIES, WHERE BACTERIA AND VIRUSES ARE MORE PREVALENT IN WATER. As such, it can be useful alone for backup or in a survival kit for use in North America or other Western countries, where the main concern with water centers around cysts (rightly or wrongly) and/or agriculcultural chemical runoff (absorptive carbon helps remove these), but requires additional chemical treatment anywhere bacteria or viruses are suspected to be possibly present.

ok, here's the deal. put this in your wish list...next time you need some $$ to get up to the free shipping...add one. then keep doing that until everyone in your family has one of these for their emergency pack.

Tablets are great and light, but still a pain to use. boiling is best, but sometimes you just can't. this is less than an ounce! It's not perfect, but it's so small and light...it will be WITH YOU when you need it. better safe than sorry. It will taste bad initially (carbon) but just spit out the first few draws and you'll be fine.

Take it from a guy who drinks copious amounts of water, this filter is the king of survival items. "Survivorman" Les Stroud has, in fact, contracted giardia in his survival adventures. Les is a teacher who's lessons are sometimes taught at the expense of his health. His lesson? Don't take chances with parasites or bacteria. This handy little filter fits in your back pocket and will filter up to 20 gallons, enough to sustain one person for days to weeks. I keep one in the car, one at home, and I never hike anywhere without one.

I've been looking for a small water filtration system for my hiking pack that didn't rely on yucky-tasting chemical tablets and drops. When I saw this on a survival gear review online, I immediately bought it. It's so small and light that everyone should add it to their camping/hiking gear, emergency bag or glove box/first aid kit. It also fits comfortably in a pocket for extreme situations when you don't necessarily have access to your other gear.
