I have never seen a product such as this and when I saw it I felt I had to have it. I can now find files faster, less hassel and my wife doesn't have to take files out to get to the one she needs. I use this on my files currently but am going to place it in her office files. I have files of all the papers on the land, surveys, permits, warrenty items and my personal files. I have told several of my friends who keep files and have showed it to several business people I know and everyone loves it. If you need a file system and want the best I suggest you give this a try, you won't be disappointed.Michael Marino
