In ways its harder to use, does not put signs in for you and does not calculate for you like the regular form.. but this is the only way I can save my form and make copies and edit it so this kind of saved me a ton of time!

Great editor, Could have some more funcationality but does 90% of what I want to do. Previously purchased another program (Soda PDF) and couldn't get my head around it. PDFfiller is soo much easier to use, with heaps of online help on how to do anything you want to do.
