They seem great but haven't tested the water yet but will soon. If it's that good/close to my old one, it's double the price of a filter. If they pass good tests, I give them 5* across the board. I bought them for camping and kept them in my bag. And I used one to teach an outdoor class, 5 gallons. A bucket is good for base camp, but not for support. Check out my tips to see how I use this filter.
