Title: Great Filter! Hasn't failed me yet!
Review: I have used the Katadyn Hiker Pro on wilderness canoe camping trips for three years now in tannin rich waters in Maine and the Adirondacks and have had no trouble at all.Recently one of my camping partners had his MSI Mini-Works fail in short order but we were able to continue on with my Hiker Pro, providing us with clean water for the rest of our four day wilderness camping trip.I tend to replace the filter cartridge every year before my spring canoe camping trips and this keeps me pumping clean water for the whole year.The provided end cap fits the Nalagene bottles of many sizes and canteen water bags easily; however I recommend optional screw on cap attachments for Platypus water bags as they make your life can be much easier when pumping from steep, muddy banks without worrying about end cap parting from the top of the bag/bottle as you hang on and pump.
