5 out of 5 stars review
These are super slick for carrying with on day hikes/day hunts. I have used one of these while elk hunting and while we use a gravity filter for when we have a small camp set up, we carry a steripen out for the day so we can refill water bottles as we are going. We have been using one now for almost ten. years and have never had any problems with water, several times in some pretty rough looking water.

Fast and light, pun intended
This is a great tool for through hikes and times when other methods don't work, or would take too long. I have used this with water from nearly frozen rivers, and summer mountain lakes and have avoided any waterborne illnesses. The only place I try to use a filter instead is if I am hiking in farmland, since this purifier won't get rid of any of the chemical runoff or from farms.

This is an inexpensive back-up
The taste of my water is important to me. This product does not improve taste, which I knew when I purchased it. This is simply to keep my water safe just-in-case. I consider this a secondary solution. Not getting ill is of primary importance so this is a good piece of kit.
