In reply to Guy:
> (In reply to Alan M) They went to a manky pond extracted water and filtered it through a sock and then used the steripen on it and drank the water. They seemed confident that it worked well and I guess they did some testing but didn't show it. In effect they said they drank bad water and didn't get sick therefore it works. Not scientific but I am sure they would have to be confident in it to recommend it on TV!
lol, sounds about right for that prgramme
Think I might opt for one the price seems good though I might wait until Im in Canada and pick one up before the trip.
