I am new user and able to start filling in some court documents even though I don't have Zero experience. Makes me pleased to use this software. In the future I would not mind attending online tutoring sessions if offered.

I've had problems expanding boxes to fit text in. Customer support sent a YouTube video and that was some help and fixed one box, but then I had problems with a second box and just didn't have the time to keep trying to fix the problem.
After a few attempts I was able to fix the problem, and now I am very impressed with the program.

I had a difficult time with it and it took a long time just to fill out passport forms for my wife and I. I just could not get the hang for it, but someone smarter than me and maybe younger, I am 72, will do much better with PDF filler.

Decent, though the affiliated linked program options which supposedly come with the upgrade purchase don't seem to work / or be actually as advertised.

Great for my online classes!
This has been a great tool for editing PDFs for my Anatomy class. The only problem is the "drawing" tool does not provide enough color options. It's very limited.
