Really good, not sure how I would be at editing large amounts of info on a PDF with the website but I could be surprised if I went through the online training.

Works smoothly and easy to use. Customer support tried to help with a "glitch" I have still not resolved. Works on my iPad perfectly but pull my docs up on desktop just sits there thinking to no end. I've just used on iPad soley since problem came up.
