It works great, but is very expensive for how often I will use it. I wish there was an option to purchase some sort of punch card or to pay per use instead of paying $20/month, which is outrageous if you are not using it daily.

I was filling out a stubby pencil application, and thought there has to be a better way. Now I'm happily dragging and dropping scanned files into PDF filler and like magic I have an automated workable document, it's fantastic.
