    I purchased this bottle after watching a video of a man in Australia use it in a pool of dirty water with dung in it, and I couldn’t believe how clear the water was after filtration. I live in South Florida and have been through several hurricanes (including Hurricane Andrew), and I wanted something for my family but didn’t want to depend on it without testing it first. Being the Guinea Pig that I am (A.K.A. Test Subject) I filled it with water from a retention pond that had severe scum on top and I could see tiny organisms in the water. I pumped the water through the membrane filter and drank about 1/3 of the bottle while at the pond. No ill effects and it tasted great, and I finished drinking the rest of the bottle through out the day. No trips to the hospital or doctor, no cramping and spending the day in the bathroom with fluid coming out of every open orifice. I’m confident this bottle will protect me and my family by providing us with safe, clean water when we need it.

    Bought it for my wife as an alternative we both regularly drink neat tapwater we get a lot of lime in our water and I do think it improves the flavour.

    Bought this bottle after a recent hike in the Lakes with the kids and realised we were running out of water, whilst all the time being surrounded by water sources we daren’t use.
    Just got back from 2 weeks hiking around the Eiger area of Switzerland and have used the bottle in mountain lakes, streams, waterfalls and all manner of water courses. The bottle performed exactly as it said it would, clean water, tasted great and none of our party (including kids down to the age of 6yrs) were remotely ill – therefore I think its safe to assume the filters work fine.
    I have noted some critism of the bottles weight and brittle construction, however I found found it solidly built, fair enough if dropped on a hard surface you might damage it – so it pays to be careful, I also bought the protective pouch. Weight wise its heavy when full, but a std 1-1.5ltr water bottle is about the same. All in all, a useful purchase which the kids loved and it encouraged them to drink more – as they got to play with the bottle. More importantly it could well prove invaluable on days when its really hot and your conventional supplies have been used.
