Pretty easy to use...so far. The only thing that concerns me was I didn't realize I had to pay for this until I had finished filling out a complex form. How did i miss that information at the beginning?

At work, I use ABBY and it is very effective. I didn't think to get that before I chose this. I was searching quickly, but am ok with it. I would to redact in groups by typing the first few characters.
