Bests & Worsts Reviews from Amazon

I used this Sawyer water filter to provide drinking water for my wife and I on a wilderness camping trip. The filter is light small and performed perfectly. We noticed nothing strange about the water or it's taste.We were using very clean looking water likely containing "Beaver Fever" and cryptosporidium. We used a 2 liter bottle as a dirty water bottle and found it to be easy but slightly time consuming to squeeze fill our respective Water bottles but still way better than carrying water in. Careful freezing destroys membrane of filter not for sub freezing temperatures. Bought this brand filter over others because of its versatility to use with straw or any soda bottle and it's long life of 100,000 gallons. Check out images of the product I uploaded. EDIT After 1 year: This filter is still working great after over a dozen backpacking trips using this filter and several hikes. It is truly very nice feeling to drink the water right out of the river or lake your camping next to vs carrying in bottled water. Have used the the syringe to clean it several times and does seem to keep the flow going fast enough. I use a filtered funnel to scoop water up and into my soda bottle before filtering to keep filter as particle free as possible. I tried to use a platypus bottle bag with this filter but it does not fit quite and leaks, 2 liter bottle works best for us. Still totally satisfied wil buy another when it plugs up.
