Love that its so easy to use. I wish it was free/cheaper since I am only using it to apply for jobs. Would be cool if there was a discount code for people in the market looking for jobs if they took a survey for market research.

It worked very well to get the 1099's printed for our wards. I am testing it with other things. Anxious to learn how to edit forms I had created when I had access to Adobe photo shop.

With recent changes, it has become difficult to navigate in the application. Also the app is slow and hence takes too much time for us to work on it. Its a great app, but due to some changes made (may be) the end user is not happy.

works, got my document, little squirrely on fill in but I figured it. It takes about 75% more time to fill in, not a seamless experience. If the typing could be done with out having to locate start character, would hlep

It is easy to use and there is no watermark which is really great when it is something that I am going to have to turn in professionally. They do a great job of making the pdf to write in

What do you like best?

What do you dislike?
Price - I find the product too expensive.
What problems are you solving with the product? What benefits have you realized?
I work most of my documents with PDF Filler.

What do you like best?
The best features are (1) the ability to easily import and that it converts with accuracy and (2) the ability to manipulate doc - more specifically merge, edit, copy, etc.
What do you dislike?
The only feature that does not seem intuitive at times is the folder structure and how the files are organized. When editing a doc it will always move a doc to the top because it is the most recently viewed or edited doc - but this sometimes makes it confusing. Similar to Outlook, it would be nice to have easier drag and drop feature for organizing the docs.
Recommendations to others considering the product:
This is a quick out of the box product, overall very intuitive and easy to use.
What problems are you solving with the product? What benefits have you realized?
Able to import and edit docs as well as having them signed online.

This symbol (called Sigma) means “sum up” I love Sigma, it is fun to use, and can do many clever things. So means to sum things up
This symbol (called Sigma) means “sum up”
Sigma (uppercase, lowercase, lowercase in word-final position. Greek:) is the eighteenth letter of the Greek alphabet.
This symbol (called Sigma) means “sum up”
The symbol means sum. Is the Greek capital sigma symbol. Used commonly in algebraic functions, you may also notice it in Excel — the AutoSum button has a sigma as its icon.
The lower case sigma is used for the standard deviation formula in statistics. The letter that looks like the letter 'u' but with a longer line is the Greek letter 'mu', and in this formula it stands for the mean, or average, of a series of numbers.
The symbol's code: You can insert symbols by typing the symbol's code and then pressing the Alt+X key combination. For example, the code for the sigma character is 2211: Type 2211 in your document and then press Alt+X. The number 2211 is magically transformed into the sigma character.
Each character has a number from 0 to 65,535. For example, the symbol for the letter A is represented by character number 65. The number value for each character is defined by an international standard called Unicode. However, the Unicode value of a (97) is greater than B (66), so the text item an is larger than B.
