    Great filter

    I bought this after one of my scout leaders brought this on a hiking trip. After seeing it work, I bought one because we would need an extra filter for our High Adventure trip. This isn't the lightest filter but to is extremely well built. We pumped about 3 liters of water before we had to clean the ceramic filter element. It made me feel good about purchasing this filter after seeing a couple more that people had on the trail. All in all, if is very easy to use and very reliable.
