PDFfiller is very easy to use and the auto-save feature works reliably. One thing that I didn't like was that I had to sign up for a plan to be able to save my pdf. Had I not chosen to sign up, I believe my work would have not been saved. What compelled me to sign up was that I didn't want to lose the work that I was doing. Overall, I think PDFfiller is a great tool and worth the money; however, some users may not like the mandatory payment in order to see their documents again.
