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.

Fan Bloody Tastic on my CHROMEBOOK, nearly real time and it would be 5 stars. Realtime not yet available in this part of Australia. PERFECT fit for 100% cloud and paperless. Love it, just re thinking it and it is now totally 5 stars. Thanks :)

The software is excellent - really easy to use. I wasn#t sure whether to pay for something I'll only use a few times a year but decided to do so simply to save time searching for free software that probably wouldn't be as good. One minor niggle: I paid on my debit card and it took me back to the website, whereupon I had to pay again to gain access - not sure if I have paid twice or not. Would have been five stars other than for that.

Great Product
This software has helped mainly with electronic signature creation but also with overall PDF edits.
The software offers a number of options for editing PDFs and is fairly user-friendly. It has an easy layout.
I do not like the fact that the software can lag when working with slightly larger documents. It can also be time-consuming to learn more advanced features.

Very useful tool
Useful app for managing all your pdf tasks. I always use this app to sign. Very recommended.
It doesn't have many free features, you have to pay for the good ones.

Creating forms has never been easy
Extremely handy tool to create forms and collect data from clients
Very important tool for creating fillable PDF forms. Includes features like highlighting, drawing and also option to place images and logos.
