I was very upset that I wasn't told I'd have to pay until after I'd edited a very long file, but customer service gave me 30 days free when I brought this to their attention.

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.

customer service excellent. removed one star for irritating Watermark and Filler buttons right next to the page scroll bar … way too easy to accidently add them … hence the need to contact support

It is a little difficult to figure out how to load an existing form with the saved name. I also had to Google how to enlarge the font. Most of the help directions are outdated, but I did finally figure it out after a lot of wasted time. I DO like the program in general and love being able to convert and save in a different format.

Very quick and easy but in the end actually only needed for a one-time use so didn't make financial sense to pay further for 'just-in-case' use.
