I was annoyed that I had to enter credit card info for a free trial. It makes me feel as if I'm being tricked into keeping your service. Very pleased with how the product works though.

PDF Filler ease of completing the form - that makes it look much more professional than a hand written form. I like the ease of being able to put all my information in on any form. The software easily moves you from one field to the next to populate. Everything looks much more professional than a handwritten form. I don't like the fact that I cannot save my form. I can print it but it saves as a blank form. Maybe I am doing something wrong, since I just started using it, but it did not save what I put in.
