See for yourself by reading reviews on the most popular resources:
I was sort of afraid to install and pay for this online. There is so much identity theft out there.. I was just a victim of fraud on my bank account. But this seem pretty secure and was easy to get going.

I found that access to and filling out of standard forms was very easy. I liked that editing and saving was also easy. Being able to log on and access your work from anywhere is a bonus

Provided files that otherwise would require me to physically write information in, this can be seen unprofessional to some businesses. Worth every penny

Following my previous comment, I found the tax forms I was working on, but they were titled by the Form, not saved documents. Taking me well over an hour due to the labeling. Need a Saved Documents Option to simplify it.

Really great product. So many of the forms I am sent would mean hours of unnecessary handwriting. With PDF Filler I am able to complete them in 1/2 the time. (The only negative is the learning curve, but once I learned how to maneuver around its great!)
