An excellent program, my only gripe was/is after paying for this program, I began to experience unsolicited X-rated and non-X rated ads. And, interference using Safari on an Apple PC

Great!! Saves me lots of time where I would have to find the form print it out and then type the information. The only thing that is a problem is the instructions within the form itself. I feel the instructions throughout the form should not be on the printout itself.

No issues once I contacted the support department who answered my questions. I understand that you are in business to make money on a service. I just felt it was costly for a piece of paper or two that would cost me 10. Cents at a FedEx or Office Max type business.

It is intuitive, easy to use, provides adequate help for new users requiring guidance, and provides flexible outlets for PDF use. On the down side, I do not require a secure connection for my PDF work, and the lag in loading and saving my changes & files is distracting and unpleasant.

Amazing! - Total lifesaver. Does what it's supposed to, and even does most of it for free (I've used it to fill loads of forms and submit documents and never had to pay for anything)! I have no hesitation in recommending the PDFfiller service.

It was very easy to use and was user friendly for using the icons to understand what I was doing. Process was a little slow, but I think that was my computer!
