I stumbled across this water filter today on Keith Foskett's blog. Does anyone have any experience of it, good or bad? I love its lightweight design and usability. It seems almost too good to be true.

On hikes, Instead of having to lug a couple litres in my rucksack from the start of the day, or risk infection from contaminated water I figure I'll just fill up the 500ml bag and swig away whenever I come to a water source (having said that, I have never become ill from drinking straight out a mountain stream or even a mountain loch so wonder if it's even worth using a filter.)
When would using this filter be most effective do you think?
