Hiking the Andes – A.H from MachuPichu
I wanted to thank you for making such a wonderful product. I just got back from South America where I backpacked from the southern tip of the Patagonia Andes all the way up through Bolivia and into Peru. The SteriPEN worked without fail even on the most questionable of water (which is found in Bolivia). The ease of use and peace of mind it provided were invaluable. Thanks again for making a great product.
