Works great, nice little addition would be the ability to copy sections of already input text and drop more copies of that same text on other parts of the page. Would make what I do ALOT easier.

I like to use PDF filler.com because I can fill the entire form on the computer, except the places where I need to sign it. Also, it has an option to fill the form on the computer or print it out with blank spaces which I can fill it out manually with a pen. Finally, I only pay for the program as long as my subscription is active.

We love the power PDFfiller gives us to export data filled in to be exported to Excel and manipulated. For the most part, it is a very intuitive program. There are some aspects of set up that are confusing, but customer support is GREAT, QUICK, and seemingly PATIENT. We are very happy so far with its performance.
