I got one of these to replace a Pur Hiker I have had for 20 years, and I am glad I did. All one needs to do is fill it, and hang it up...that's it, your water making chores are done. No more pumping, lol. I used it on a 5+week trip last summer in Minnesota and Ontario and it worked great, with no problems at all. It is light weight and packs small too. You will need to back-flush the filter on occasion, but that's it. It is a well built, solid piece of kit, and was a pleasure to have along.
