I am a slow learner...give me more time.I am 68 and not internet literate. It's better for me to fill out Government Forms through PDF Filler than in my own handwriting. It look very professional and understandable. It's like I got a Secretary. I would like to learn more about faxing and emails.

The service produces a very handsome document, and facilitates changes when necessary. I had a little trouble navigating back and forth between the document and the print function, but that may be attributable to my lack of familiarity with the product.

What do you like best?
The program is user friendly and helps me with the essential tools I need to fill in and change my PDF files. I use this on a daily basis for work and works very well with other programs I use.
What do you dislike?
The font match is the only downside of the program i face especial when I have to fill in words and characters onto the document. It takes time for to match the font that is similar to the original font. Collating pages in a certain order is difficult for me but I decided not to use this feature.
What problems are you solving with the product? What benefits have you realized?
I am facing no problems using the program. The main benefit I use this program is the editing of the documents revived for out business to use for our needs.

They were super helpful to me when I… They were super helpful to me when I accidentally subscribed. They voided the transaction and were understanding. I really appreciate this because there are too many other automatic subscriptions that would not have been as forgiving.
