So far so good!My first transaction on PDF filler. I would say that the passwords and pins are a little confusing for people. Also, brokers don't recognize PDF filler for authenticated signatures. They accept Docusign. I use PDF filler mostly for the ability to make my PDF files fillable and then I transfer them to Docusign. So I do find PDF filler VERY useful.
