PDFfiller was intuitively simple to use in creating an important document. I had difficulty erasing some text I accidentally superimposed onto my document and the recipient who ultimately got the PDF I created could not open it. Also disappointing was the fact that I didn't realize I had to pay a tidy subscription price until after I completed my document and tried to send it off (and save it). That all led to an initially horrible review. But, I have to say that my experience with PDFfiller and Elie, the rep I dealt with, revised my entire experience. Not only did Elie help resolve the problems in a very timely fashion, I received a refund! PDFfiller seems dedicated to provide the user an efficient product and the customer service is the best I've seen with any internet-based business. Elie is a great ambassador for the business and she really follows through with her promises! I never expected that. They are also going to revise some aspects of the user interface to ensure proper notice of expense and conditions of subscription. I will certainly use PDFfiller in the future!
