Pretty good so far. Was a little surprised that I had to pay once all the work was done. But its okay, have used it a couple of times and its working.

I'm happy with it for the most part. I think it's BS that you allow the eraser to be used on the 1st document and only when the customer goes to use it again, do you mention that it's an upgrade is bad business!!!!!! There's another issue but at the moment it escapes me.
2016-08-19
I like it but wish there was an edit instead of erase and text to change something. There may be but I'm not aware of it so a webinar would be very helpful.

Filling PDF files for formal use
The product is very easy to use and intuitive, I didn't feel something was missing from my work with the application, in addition, it's global availability is a great advantage.
The product offer mainly online editing, which makes it hard in case you wish to work on the flight or just go offline, in addition, the free use is not exactly free as it asks for a payment prior the file conversion.
