Excellent tool, very useful and easy to use In my work we use a lot of PDF for contact with the client and the truth is that it is useful to have such a tool to make it quick and easy; It's something less to think about. The best thing about this tool is that it solves a basic problem with the PDFs we receive: editing them. It is also very easy to use, saves a lot of time and has the possibility of adding a digital signature to each document. Some form formats are more complex to edit and the tool gets confused, but it happens with all other tools.

I've used their software and it's extreemly good. But what I liked most about their company was their integrity. Twice our auto renewal popped and most companies would use this as a gotcha moment to take your money. Both times we didn't require the auto renewal they credited within 2hrs of an email. Amazing customer service and great company integrity. Would reccomend to anyone.

It has been pretty intuitive. Had some issues with a long 70+ page doc at about page 50 it was going blank. Help chat sorted me out telling me how to delete cache which sorted this.

Spelling assistance The spelling check assistance is not very effective. It is difficult to predict where the cursor must be placed for the correction suggestions to pop up.
