The experience before I purchased a license was not so good. The chat session I was on kept ending. The CSR said because I was not logged into an account was the reason. At that point, I was trying to determine if I even wanted to purchase PDFfiller or not so why would I need an account. I finally ended up purchasing the product.

the biggest difficulty I have is when I am trying to re-order documents (move them left or right) -- it is just very difficult to see them. I wish the functionality allowed for enlarging the docs so that I could see what it is.

Easy, reliable and very effective
Makes completing forms easy and professional. Easy to navigate, easy to find and upload forms and easy to send/save.
the only negative thing I could say is that I would like to have the font a different size and I have been unable to fit it correctly in some spaces.
