Review title: It worked...
Product review: It's impossible to tell if things like this work because if you don't get sick, you don't know if the water was infected or not. Nonetheless, on my last backpacking trip I planned on getting water from a stream that I saw on a map.The stream ended up being extremely low, almost dry actually. The water was brown, almost completely still and very sketchy looking... I was pretty reluctant to drink it but I didn't have any other source of water for the trip.I filled a 40oz container and added the pill. Waited 4 hours and drank the whole thing. Then got more water for the rest of the trip. I didn't get sick so it must have worked!
