I’ve had several of these over the years, they work amazing. I picked this one up a week after a camping trip when my last one finally broke (Not a product flaw, my fault, slipped and dropped it on a rock near a stream, cracked the housing). So when I got back to town, I replaced it. I didn’t remember that I actually already had one in another bag of gear. So this one, brand new and never been used before, gets to find a new home. I have so many ways to filter water and so few times I actually need to, hopefully this finds use in your collection.
