i had a hiker and loved it. Wish I knew where it went. So I needed a new filter and decided to upgrade to the hiker pro. It is just as reliable as the hiker with some added features. I love the quick links it has. It makes connecting everything quicker. I ended up getting some tubing from the hardware store and modified it so I can quickly change between hydration pack filling and filling up a nalgene. I will try to get some pictures of this up, but this little modification makes things so much easier rather than having to wrestle with getting the hose on the adapter you want to use every time.
