Have used it to fill out two forms and was very pleased with the experience. The only problem I encountered was being unable to expand the circle. May be due to my not fully understanding the program's capabilities.

Auto Renewal Charge
I was auto charged for a 2nd year for this service via PayPal. I do not need it and was surprised to see the charge. I contacted customer service via chat and they immediately issued a refund with no questions asked. I received an immediate email confirmation. That is customer service. Thank you pdfFiller.
