Things have been good. The only thing I wish it had from the main screen was the ability to save the document as a different version from the forms page.

At first, I didn't understand what I needed to do first. I filled out the form I pulled up and then submitted it, but was sent to a page to choose which plan I wanted. When I realized I needed to choose a plan, I chose one, but then I had to fill out the form all over again! Then I submitted it, but the form again, but it wouldn't appear on my list of filled forms. My list only lhad a previous form from 7/15/2015. I chatted with a representative and she helped me get my second version on my list. This rep was extremely patient and nice, and did all she could to help me. I'm very happy I spoke with her.

PDFfiller has been an excellent tool for both personal and professional uses. I especially like that I can send documents and get a confirmation receipt once the recipient downloads it.

Highly will recommend to others. Easy to use, and I just enjoy the fact that I can edit the text box to where I want to put it and being able to change the size of the box. There are ,of course, more features, but this is feature by far has been the one I been using the most.

Its ok. It would have been nice to know that you would request credit card info before being able to save or print your document. Thats bad faith and almost akin to blackmail, considering a Govt agency has you approved as a trustworthy company to handle sensitive information.
