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.

PDFfiller has exceeded my expectations.
I regularly have a need to complete and to apply signatures to PDF documents. PDFfiller is a real time-saver in that it eliminates the need to print a hard copy and then manually complete, sign, and scan the PDF documents. Also, the PDFs that it creates end up looking much tidier and more professional. As a bonus, the software saves and maintains a duplicate record of all my PDF papers.
I originally subscribed to PDF Filler, under urgent circumstances, simply to be able to apply a verified electronic signature to a single document. But I've been awed by how versatile and useful it is. I now use it almost weekly. As a business owner, PDFfiller has been a great value. I'd recommend it to anyone who has an occasional or even a regular need to edit and to apply signatures to PDF documents.
There's really nothing about PDFfiller that I don't like. This is highly unusual for me as I'm not the most tech-savvy person and I frequently end up frustrated with software.
