Just testing it out...but..so far seem to love it
I am just beginning to use it for the first time so I really have not formed much of an opinion
It has helped me out with applying for jobs and not knowing where to get the forms.
Good company with a great product
This is a good company with a great product. I am a retired attorney who was in need of a certification of trust for our family living trust. I checked pdfFiller and found what I needed but then realized that in my experience as a lawyer, I already knew the basics of what had to be done. So I cancelled the subscription and within minutes, received word from pdfFiller that the subscription would be cancelled. An honest company that is responsive, with good products - can't do better than that.
