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.

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.
