It seems to be pretty straightforward. I have trouble saving it to Word and printing it but I can just print it from this program and it turns out perfect.

I am retired and use it mostly for medical forms. A little difficult to learn how to begin but once I figured it out everything worked just the way I wanted and I learned more as I went along.

I hate having to type in a verification code when I leave for a bit. I know it is fro security reasons, but I would really appreciate it if you did not make it type the code.

I really liked the entire PDF Filler platform! The content was laid out clearly and it was really easy to get started (even when I was frazzled about other things). Working with the platform in seamless and I have already recommended it to my mom who uses PDFs in her company 24/7

What do you like best? Ease of use and broadness of applicability. What do you dislike? Its ease of use and broad applicability trumps any minor issues. I am not aware of any significant issues encountered. I evidently need to keep typing, because I'm not able to finish this task otherwise. What problems are you solving with the product? What benefits have you realized? Being able to fill in PDF's without using more expensive solutions. Also used to authenticate signatures in various ventures. Comes in extremely handy actually.

The software could use some updating. It is not the easiest to edit the document. The app also kept crashing on me and I had to start all over again. It was very frustrating.

A very easy to use program A very easy to use program, though you are forced to sign up for free trial if you want to print any documents.It did what I required, so cant complain. Just would prefer it to notify of unable to print unless joined up for 30 day trial before I spent 4 hours working on translation document.
