"Tries to install other programs, free version useless"
It's exactly like Acrobat, without being Acrobat
Tries to install other programs, and is persistent about it, doesn't even ask, you have to catch them and manually hit cancel on the dialog to stop it. Bad manners PDFill.
You still have to pay for it, Otherwise it puts huge obtrusive watermarks on your output. Don't bother unless you're going to pay for the full version, in which case you should just get Acrobat and skip this. You'll get more support that way.
No idea how this got so many good reviews.
