This sorter makes piles of papers so much more manageable. On the the one hand, they're so simple and straightforward it seems like there's not a lot to say, but if you've ever faced an abyss of paper filing you can't over state they're value. Also it will considerably consolidate space. I use post it tabs over the provided options if I'm working with subjects rather than dates. In my experience they are sturdy. They are not water proof or resistant that I am aware so keep your coffee on lock down!
