Great editing. Could use some better freehand options
All the editin options are just soooooo practical and useful. i really get work done fast.

Marie from the Customer Support Center worked with me promptly to ensure I received a refund. It is not that I was not satisfied with the program, it provided me with everything I needed to complete my work tasks remotely. However, I am on a limited budget and took advantage of the free trial opportunity. My intention was to cancel my subscription prior to renewal, but unfortunately I experienced a death in the family and was unable to cancel in a timely manner. I noticed the charge on my account today and immediately contacted PDFFiler customer support. Within 10-15 minutes of my request, I received confirmation that I would receive my refund. They were very understanding and accommodating.
