I am older and my hand shakes so badly I cannot fill in forms -- it is a real life-saver, not to mention time-saver. I don't have to call someone in to fill the forms out for me, I've already recommended PDFfiller to a dozen friends!

The program did not function as I anticipated, but after I played around with it, I realized it was still a useful tool. I am a Licensed Counselor and this is a great tool used to communicate and transmit sensitive information online. I highly recommend to others!
