Title: Works great
Review: So we took a big trip to North Manitou Island to spend a couple days in the wilderness and brought this along with us. After about 5 miles on the second day we were pretty low on water and were smack in the middle of the island. We found a big pool of sitting water, it was mostly clear but had a lot of algae growing around it. I was pretty nervous about drinking from it but we had another 5 miles to the nearest water source and 30 lbs of gear. We used this filter and never got sick from it so I am a pretty happy customer.
