The software worked great but didn’t… The software worked great but didn’t quite fit my needs as a student who uses pdf editing 90% of the time to write with a stylus for exams. The reason I gave them 5 stars is for customer service. They were very kind and helpful when I contacted them about my account.

I mislead them on my intentions for the service level that I required. Once I brought it to their attention, I answered 3 questions; and the matter was immediately resolved. Outstanding customer service comms. !!!

Chatted online to cancel and refund $96 that I was charged and I got a pretty friendly guy named Peter! He was sweet and fast! If I needed this particular application again, I would definitely reuse them!!!
