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.
What problems are you solving with the product? What benefits have you realized?
Verified signatures and completing PDF documents.

Excellent support and customer service I registered for an annual membership, but I didn't pay attention that the membership fee is calculated in US dollars. I live in Canada and it was expensive for me. I emailed support department to cancel my membership and they responded in less than an hour and sent me a full refund. I appreciate the excellent customer service and proper support, polite and professional behavior of the staff.

great product, "home" and "end" keyboard keys slightly buggy All is great except that when im typing in a text box and click the "home" or "end" key on my keyboard it sends me to the beginning/end of the entire document instead of the beginning/end of the text box itself.

I mislead them on my intentions for the service level that I required. Once I brought it to their attention, I answered 3 questions; and the matter was immediately resolved. Outstanding customer service comms. !!!

I love the product and help via chat has been great but it would be nice to have some training videos to help me get up and running with the product. This is my busy season and it slows me down having to chat for help a video would be so much nicer. Thank you for a great product.
