Expensive for irregular user but overall excellent! Expensive if you are an occasional user, and I wish the "fill in the blanks" were a little more automatic with alignment. But overall excellent!

I started with pdfFiller almost a week… I started with pdfFiller almost a week ago, and tried to get support on and off. The Live Chat didn't work, so I was emailing, but the emailing didn't really work as I would wait for a response, and when I got a response, I was working on something else. But the Live Chat did work today. The first person was trying to help, but I didn't know how to do a screenshot and he got tired of waiting for me to do it and ended the chat. Then, I got KARA, who was fantastic. She did a Zoom meeting and showed me how to do everything I want. I am so relieved that I understand how to fix my problems, and I was just about to give up until Kara got on the Live Chat. She was patient and informative. She is a rock star!

I love the product and help via chat has been great but it would be nice to have some training videos to help me get up and running with the product. This is my busy season and it slows me down having to chat for help a video would be so much nicer. Thank you for a great product.
