What do you like best? How easy it is to use, the signature function too. What do you dislike? History saves only one document and can't change it. Recommendations to others considering the product: It's great, so don't hesitate What problems are you solving with the product? What benefits have you realized?

Very useful! What I most liked is the signature with verified by PDFfiller. There are couple of times I cannot edit properly but this should be how the pdf file was created. For example, to change page number, I wasn't able to do this properly so end up sending my forms as they were.
