originally i was dissatisfied with paying $20 to learn how to use the system and still did not get any benefit. Then customer service reached out to me to provide assistance and work on a solution. I am still learning how to effectively use it but am happy for their willingness to help.

What do you like best?
I am able to create and update PDF files easily. The newer/updated features are wonderful. (ie. font colors and actual fonts)
What do you dislike?
Haven't had any issues that I can think of
Recommendations to others considering the product:
If your company handles PDF files on a regular day to day like mine this is a must-have. From removing or just moving pages to changing/adding the text. I use it daily and haven't found another product that compares. Even Adobe Acrobat doesn't compare.
What problems are you solving with the product? What benefits have you realized?
I can update items that have been delivered to me in a PDF format that I would have issues with normally.

Sign it! In general is a very good option to fill and sign documents. I did not buy the paid version because I was in need at the moment and it worked perfect for me. I like the easy to follow process of this software. You dont need to know how to use it. As soon as you start filling any document everything march along the way I did not see any cons because I was able to resolve my needs with the free trial. I would hesitate to pay for this software if I need again.
