What do you like best? I like the fact that PDF Filler is available on the fly whether you're on your phone, iPad, or desktop. It's easy to sign, fill out forms, edit, etc. What do you dislike? I dislike the load times when opening a pdf document. Also, I do not like the fact that I cannot automatically send a pdf to SignNow without having to logout and log back into PDFFiller. What problems are you solving with the product? What benefits have you realized? I use PDF filler for all my real estate transactions. Because I've pre-filled all my personal information, it's easy to just substitute the rest of the information on the forms. It makes life a breeze!
