It is expensive. You need to reduce the annual price. I also do not like the way the eraser works - it is either very sketchy or one has to save a doc and reload to erase something just done. Very slow and clunky

I like the fact I can do this online. But, being new, it's complicated finding my way around. I cannot figure out why the font changes size when completing column J - both lines.

Very intuitive and easy to use application that provides a high standard product. Much better than other applications on the market that I have tried in the past.

This is a wonderful software to use This is a wonderful software to use. No more paper-printing and scanning in. I just do everything electronically, it saves the environment as well as a lot of time.

Basic PDF Editor I use it for PDFs for our Escrow files. We have clients sign docs and we can make changes to anything that they send us and then send to them to sign off on it It is easy and very good for a basic PDF editor. You can make simple changes and save it so it looks exactly like a PDF should. You can add and edit text, highlight, adjust sizing, etc. It is too basic but i understand that it is not Adobe. I wish I could edit the text that is in the PDF more easily to make it match and all look seamless
