PDF Filler makes it so easy and efficient to complete any document. I will never go back to handwriting, it's just a lot neater and clearly stated with PDF Filler.
Anonymous Customer
Easy to use, but sometimes doesn't show exactly what I need with form being listed under another name or title (e.g. a search for DA 31 gave me the AR 600-1 132 page doc but not the Leave and Pass Form).
Paul A. H
Great!! Saves me lots of time where I would have to find the form print it out and then type the information. The only thing that is a problem is the instructions within the form itself. I feel the instructions throughout the form should not be on the printout itself.

Don't quite understand how it works as I am not a computer person except to do genealogy, and write. One cannot operate a computer without it. At least this is what I'm finding out. It all seems automatic, I would like to know more about it's function, Why's and what-fores, instead of just logging on and it appears. All I know is that it is a major function for downloading photographs and some documents. There should be a tutorial offered to those who are senior citizens and so many things are automatic. It takes understanding its function to a non-software-computer person. Guess more instruction would help.

Convenient, fast and legible. It is easy to complete the form by flowing the wizard's help. It is legible and neat for reviewer's to read. It is fast and easy to upload and download, and finally signing with an accurate date/time stamp.
