I am surprised this discussion is still happening. That said, people keep mentioning boiling water. Has anybody here, in real life, done this? I have. I grew up in the wilderness in an era before we had The Internet. Boiling water may make it safe in an emergency, but the water is NASTY. Distilling makes clear, safe water. Filtering and boiling make it clear. If you simply boil water that has other things in it, those things remain, even if neutralized. Games always get this wrong. Heck, they had to slap a warning on "The Long Dark" stating that it was a game and not a replacement for real survival training due to facts like this.
As such, the dew collectors produce FAR safer water. As for the jars, I could take or leave them. Played with them for years and while I miss them, it's one less thing to scavenge and worry about.
