What do you like best?
I used PDFfiller to complete PDF versions of scholarship applications and it was such a time savings and so easy to work with that it was worth every penny. Since that time I have found many more features, like the verified signing, that it has become a necessary tool for both work and personal use.
What do you dislike?
Not really anything I disliked. I think the price for a personal user is a little expensive.

I initially thought that PDFfiller was a free tool unless you actively initiated a subscription. Even though they asked me for my credit card information with a free 30 Day trial I forgot about it. When I got my next credit card statement showing I had been charged for the whole year I began a ticket with Customer Service. They were so kind as to immediately understand, cancel my subscription, and agree to issue me a refund. At the time of writing this, I am awaiting my refund as I just requested the cancellation today - but I must say that this gesture was amazing by PDFfiller and this review is the very least I can do. Thank you for brightening up 2020 a bit! Amazing business ethic and professional courtesy.
