I wanted to get the discount and pay for the whole year, not sure, it wasn't clear weather I actually paid that way or am paying for a month at a time? Need to make that easier to understand and make sure you are paying the way you want for the discount. You can do a follow up survey only if you are on the line when you call -

The log in process is a little clunky. I have not been able to copy paste a field in the template creator. I have 30 fields or so that will each have the same sized field, I should be able to duplicate the specific field a number of times and paste. No?

Definitely Useful
As I mentioned, it makes the mailing process much more efficient.
PDFiller allows you to create and mail PDFs easily, saving you the hassle of getting an envelope, purchasing a stamp, maybe having to go to the post office, etc. For me that has been its greatest strength. The PDF customization interface isn't bad, but it's not immediately usable. It takes a little bit of time to learn how to use it effectively.
Right off the bat: I would not recommend this software to someone who isn't tech savvy or doesn't want a bit of a learning curve, for example, employers I've had in their 50s, 60s, and 70s who don't really "get" technology. The interface is fine if you just want to sign a document, but is not particularly intuitive when it comes to doing simple things like outright deleting portions of text. Too many steps.

It's very easy to create
It's very easy to create, edit, share, get website code, and sell these forms. The reason I am giving a 4 star instead of 5 is the price.

Great program for the price. I save many documents as PDF's and there ar times when one word or sentence needs to be changed. It is so simple, open the doc, make the correction and save,

Love it
It's the easiest app I've used when it comes to filling in forms. Simply save your form in your files and export or attach to the App and it's self explanatory
No cons
It's point click and fill in. Can't go wrong
