At first, I was outraged that I had wasted 2 hours to fill in a form, only to realize that I couldn't afford what they were asking for me to print. So there was 2 hours wasted. I sent an email to PDFfiller, explaining my outrage, but then they gave me 30 days free! So I could then print out my form, it wasn't a waste of time after all! Great customer service.

Alycia B
I'm working on several files for which I need to be able to type in the answers as my hands have arthritis in them and that makes it difficult to write. The instructions could be a little clearer. To be honest, I'm a new widow and I wasn't thinking very clearly. I haven't taken the time to read the online instructions so my navigational issues are of my own neglect. I think you have a wonderful product actually.
