Well, I bought this item with some excitement thinking this was my answer to using chemical tablets and boiling. Was I wrong. I read all the positive reviews and watched the videos and thought this was my answer to hiking in the wilds and minimizing weight. When I got the item I followed the instructions to the letter primed etc and noticed small deposits of carbon from the filter passing and settling at the bottom of a test glass, but put this down to it being new. Went away for the weekend and… Full review
I received my bottle yesterday and I read the instructions and primed it. The bottle works very well. It doesn't explode or choke your kids and you won't void the warranty by filling it with orange juice — provided you RTFM!

I have not field tested the bottle yet, so no comment on practical use. Full review
The LifeSaver 4000 Bottle is a cinch to use, easy to carry and very practical. Simply dip the unscrewed open end into a water source, close the end cap and pump a few times.

Absolutely no trouble whatsoever and it supplied water for 2 adults, our eleven year old daughter and 13 year old son. We dipped… Full review
It doesn't work — we used it in Canada. Carbon filter crumbled nearly choking my 5-year-old. It leaked everywhere and we still got Diarrhea. On our return we investigated this British company, they pretend to be humanitarians but are not. Don't buy these products. I'm too upset to write a detailed review. Full review
