"I have been an avid fan of PDF annotator for six years (I'm in science research). So I just wanted to email you and say THANK YOU! Thanks for creating such a great program and for making software that is so user friendly. As a consumer, I really appreciate it and you are definitely the exception in the field."

"It is really a great aid to instructors. I have my students turn in papers in PDF and then I grade them on my tablet. It saves me from carrying around hundreds of pages of printed material. I would strongly recommend your program to college instructors."
