I was refunded the automatic annual renewal charge by customer service representative after stating my frustration that I was paying for a service that I no longer needed. I greatly appreciate being treated how I treat customers! Thanks

I love the program. The smart folder...not a fan. Do not like that we have to "tag" them and I would prefer to just make and name my own folders and move PDF docs into them as I wish (like windows mail).

All i needed was the Rewrite PDF mode, All i needed was the Rewrite PDF mode,but you hide it took me almost 30 minutes to find this.And almost get out from this site..if you see i'm uploading a PDF file, suggest me the rewrite mode from within the Preview mode, (or on right click on the document - with the remove to trash and all the other options)

It's cheaper than Adobe. It gets the job done and has many options for filling out PDFs. I use it mostly for the Army National Guard and now as a substitute teacher.
