Never go camping without it!!
Got this a year ago before a camping trip out to Yellowstone. Worked absolutely perfect in the backcountry. Water was crystal clear and tasted just as it should. Also a lot faster than I though it was going to be. Easy pumping motion makes it easy on the arms when filling a couple water reservoirs for day hikes. Cleaning is cake just take it apart and let it dry. Recommend this product to anyone!!
