Rated 4 out of 5 by Cduff filters great! but..
we two of these with us when my instructor and i were guiding backpacking trips this summer. they filter great, they provide good clean good tasting water as apposed to some of our older units that made everything taste kind of metallicy. loads better than using iodine. the only problem we had, and it was a pretty big one, was after about 30 strokes or so the element would get so clogged up it wouldn't produce anymore. we switched back and forth between the two, while one was pumping i was cleaning the other, and took probably near 2 maybe 3 hours to pump 2 gallons. the water was drawn from a moving well and looked crystal clear but the elements would be caked over with grit and mud. honestly there was probably an error on our part, it was our first putting using these. if anything, its a testament to how well they filter. I'm sure drawing from a faster flowing source would provide better results. because it was probably our fault only one star down.

Rated 5 out of 5 by OutdoorMatt Very Happy
There's a never ending debate over water filtration & treatment on the hiking forums - filter vs chemicals vs nothing. I've chosen Aqua Mira tablets in the past, but that does not filter the water. Call me picky, but a bandana does not cut it for me. I'm also hesitant about using chemicals. I initially avoided pump filters because of perceived complexity and stories of clogging. I did my homework and found this MSR MiniWorks very simple in construction and maintenance. Use: The filter is easy to pump, and fills a Nalgene bottle in a reasonable amount of time. I take this on overnights, day hikes and when traveling.

Rated 5 out of 5 by Jimmy137 Great Water Filter!
Me and two others went on a 3 day 21mi trail up Bomber Mountain in the Big Horn mountain range near Buffalo, WY. Filter worked great it just took time to fill the bottle up. We quickly found that this filtered so great it was catching alot of particles and needed to be cleaned frequently. A quick scrub fixed that problem. Simple and compact couldn't ask for more in a filter.

Rated 1 out of 5 by usuf Broke 2nd day in the backcountry
Like the title says, this filter stopped pumping water after the second day of average use in the backcountry of algonquin park, so we went back to boiling water. It did make some fresh, clean water when it did work though.
I'm now interested in some sort of gravity pump where you fill it up and forget about it.
