I like everything I have tried with the exception of the fact that I cannot download a fillable form to my desktop. I wanted to make a form that I could pull up quickly on my computer when I have a new patient intake. It only allows a link and too many steps to make this a good alternative to the paper and pen format I am currently using.

What do you like best?
How easy I can manage PDF documents (fill, convert to an Office document, and signatures). I'm very glad!!
What do you dislike?
Nothing, it's easy to use and fast. I recommend this tool to anybody.
What problems are you solving with the product? What benefits have you realized?
I work in a Legal Department and we review a lot of contracts on a daily basis. Most of the documents came in on PDF format, so using PDF filler to convert the file to an MS Office is easy.
