Familiarity: I've used it several times
Purchased this filter after hiking with a friend that had one. Just completed multiple days on the Teton Crest trail and it worked like a charm. Filters water quickly, easy to use, no funny after-taste. A little heavier than some of the others but worth it. PS Keep the in-take off the bottom of lake or stream so filter doesn't get dirty as fast.
