The stars did not appear on this survey, so nothing is marked; however, this was and still is a great service, and is very much needed as it is a very helpful tool in filling out forms that do allow computer input. :-)

At times, it is difficult to edit the pdf the way you want. There are too many steps to take in order to do what you want with your document. Eventually, I am able to get the pdf the way I want it.

I sat down and began using it right away without any tutorial what so ever. It's just that easy. Looking forward to learning what else this program can do.

For the most part, it is a helpful tool. However, I will need to cancel my initial free subscription because one of the documents I would be using on a bi-weekly basis would be for payroll purposes. Unfortunately, when I scanned the document, I was not able to enter numbers in the fields. After several attempts, I checked the hardcopy document and it has a feature, which requires an applicant to fill in the document with a blue pen, something I was not aware of ahead of time. Evidently, the company had the documented protected to only read "handwritten", blue pen entries. I would be using the document as mentioned above for other candidates on a weekly basis and since this product, through no fault of its own, won't allow me to do that, it doesn't serve my business purposes.

So far all worked really well, the only thing that could be still improved is to have the possibility to change the font size, when filling in a document

What do you like best?
It is very easy to use and available for mobile app. Constantly improving and mobile apps features have improved a lot and seem a lot of functions than before.
What do you dislike?
People don’t know the program, so they are afraid to open when i send to request a signature.
What problems are you solving with the product? What benefits have you realized?

Great tool Easy to use and has functionality I need. Think there is some maximum number of pages you can convert at one time so have to break it up.
