Works extremely well Super easy to figure out Very intuitive On the minus side I don't have enough PDFs monthly to justify the cost. Maybe there could be a 'per page cost' for the infrequent needs.

Hard to find the erase button. But after I asked, I found it buried in the "tools" --seems like it should be more visible. Love the tool's simplicity otherwise.

Great SAAS for individuals who want to archive and update forms periodically. Final product is neat and most of all easily validated with digital signatures.
