Exactly as amazing as people told you.

This thing is no joke! I took it backpacking on Maine's Bigelow range. When I ran out of the water I brought, I was A-ok with this. Just bring a wide mouth bottle to fill with water you find. On top of one of the lower peaks, I drank from the most disgusting looking crevice filled with brown scum (see photo). I thought, this is going to be safe, but taste horrid. WRONG. TASTED LIKE THE FRESHEST SPRING WATER. Better than any tap. I'm from Maine, and I've tasted plenty of water right from mountain springs, so take my word. One caution: it can be a little challenging to start. You have to prove it by soaking. If it still doesn't work, blow into it a bit.
Get one for your outdoor adventures, and one for your bug-out bag, which everyone should have in case of natural disaster (or apparently civil war, because the world seems to have gone mad).
