What do you like best?
I enjoy very much that I can scan in documents and then fill in and add things to them easily.
What do you dislike?
Very little. But sometimes I find I accidentally click on the up/down bar instead of the buttons. Also, some of the buttons are not intuitive, but trial and error works well, and mistakes are easily deleted.
What problems are you solving with the product? What benefits have you realized?
I used to need a type writer (or hand write) sometimes still to comply with using the forms given to me by the government. Now, I can upload them and use the computer. Much better.

What do you like best?
I have been using PDFfiler for more than 4 years. It makes my pdf documents look professional. There is no longer a need to print a doc, fill it in with pen, scan, and send. PDFfiler reduces the amount of steps I have to take to get the job done. It helps to also have everything saved on the My Docs page. I can find the same tax documents I need month after month. PDFfiler also reduces the amount of paper needed to generate a document. I probably use PDFfiler every day.
What do you dislike?
I would like to be able to turn off the assisted pop-ups. They can obstruct the box I want to enter text.
Recommendations to others considering the product:
Simple to use. Makes your docs look professional and neat. Easy to manipulate a doc that is incorrect.
What problems are you solving with the product? What benefits have you realized?
I fill out every form on PDFfiler. It's automatic to me. In addition, when I am unable to edit a Word doc or other pdf, I know I can upload it to PDFfiler and get the job done right away.
