Wonderful overall as it allows me to type instead of hand write certain forms. I am hoping that it will be easier to use to line all cells up so it looks more neat.

Great experience, have to redo tax form sent and was not able to fill form out with other downloaded program. Have it done a printed now running to post office, needs sent out ASAP.

Definitely an aid needed in my industry for State regulatory data gathering forms. Tedious and every facility utilized the 35 pg form differently with no consistency. The tool is also very physician specific though as a Nurse Practitioner a good degree of crativity is required to enter the desired information that has no technical heading/home within the document. Adding pages and making duplicates is key as it often required, especially with added clinical experience and with work history. The ssimple 35 pages easily grows to over 60 at times.

PDF filler has been a true hero for me and my daughters competition projects and has placed first! It is very easy to use and convenient! I love how there are many options for fonts and sizes and how easy it is to print the document and save it! Sometimes when I print out the documents it is really tiny and hard to read. This is the only con to using this product that I can think of.
