Title: a note on longevity
Review: prior versions were impregnated with iodine and lasted me about 4 years of hiking about two weeks a year - that's a lot!not this. lasted one year, clogged on a mountainside.at nearly the same price as aSteriPEN Traveler Handheld UV Water Purifier(which is on sale for forty bucks today at amazon), the writing is on the wall for Katadyn. UV + backup chlorine tablets = lightweight, dependable, quick and cheap!
