Perfect PDF Ultimate

If you're looking for a decent PDF editor, pass. Interface is clunky, highlighting and pen is buried, menus make no sense. Also doesn't allow windowed view, i.e., does not allow you to split screen open two instances of the same doc... critical for technical docs where you want to annotate a figure while reading the text. there are far better and cheaper editors in the store. This isn't terrible, but others at half the cost are at least as good. If I could return it I would. Edit... to be fair, I'm using this on a surface book in tablet mode. Maybe it's better with keyboard and mouse.

no instructions, no support....don't buy!!!!!

I don't care for the software. It isn't powerful enough. It's also not user friendly or have enough options.
