Mark Young wrote a review of First Need XL Water Purifier on March 31, 2003
The First Need water purifier was an easy choice for me to make. After two consecutive years of backpacking and elk hunting with a "seasoned" backpacker friend (into wilderness areas) who carried his everywhere, I saw first hand the value of a dependable water filter. Not only is it a true purifier (we drank purified lake water), but it also is durable and Nalgene bottles screw right on it. I was fortunate to see the First Need purifier operate in the field and I anticipate years of service from mine. Thanks for carrying this high quality product at a great price.
