I know a woman who bought one. She loves to play with electronic stuff and software. She said it worked very well and she was glad she bought it. I haven’t seen the woman for a couple of months, so I don’t know if her opinion still holds.
My filing system is simple. I pile it up on the desk until it starts bugging my husband, who then files every thing in the proper location. Simple. (I’m grateful that he’s willing to do that because he’s much better at organizing then me).
That causes a bit of anxiety from time to time but it works.
