User Review: Katadyn Base Camp
Price Paid: $59
I bought one of these for a trip to the Buffalo River and it worked great. Fill it up and let it go. We probably filtered 20 gallons of water with no problems.
One potential fix for the problems people have noticed about it not working at first. I experienced the same issue when I first hooked it up to test. Nothing came out. I gave the bag a slight squeeze and voila...the water flowed. From then on, it worked well.
