I have not been able to figure out how to use my mouse and just scroll/roll thru the doc. I have to go to the left and click on page 2, to get to page 2, I can't just use the roller on the mouse to move.

pdf Filler is surprisingly worth the investment pdf Filler is surprisingly worth the investment. I don't have a PDF application on my computer, so having one online that I can easily use to view, fill, and send documents has been a huge help for work and personal use.

Quick sign up, User friendly for beginners and love the functionality!! What made my experience great is that it was simple and easy to use, I had only used docusign once before and decided to try pdfFiller for some court papers that needed electronically signed immediately. It is super user friendly. Great pricing after the 30 day free trial. But my favorite part is the set up and how many different things you can easily do!!!!
