Am new to PDFfiller so here are some initial comments: 1. an "undo" button would be nice 2. when sharing a document and adding comments/instructions, it would be helpful to have the option to pull up the document to be shared for reference.

Excellent Customer Service from PDFfiller staff, Kara I will never forget the exceptional customer service i received today, July 27, 2022 from Kara, a staff of PDFfiller. I literally went from tears of sadness for not being able to trace the document i had worked on since morning, to tears of joy & fulfillment. Having met an online angel like Kara, my hope and indeed, document was restored, She went over & above the call of duty to ensure that i was delighted in the most patient and excellent fashion. She is worthy of commendation and has greatly affected my first impression of PDFfillers. She was exceptional, skillful and most amazing in resolving all the issues i ever mentioned. Thank you so much, Kara, your type is rare. Well done PDFfillers!

It was tough,but I think I got through it. Nice to know that I can contact help if I need it. This might work better than Adobe verison. it's more affordable.

What do you like best? The ability to send PDF's for signature and manipulate fields... What do you dislike? sometimes the automatic field mapping can be quirky and when people sign documents it may not be the most intuitive set up. What problems are you solving with the product? What benefits have you realized? Having to print out paper to just to sign and scan back. Also, due to the pandemic and less people having in person meetings this can be used to sign documents even when you are not face to face with clients.

definitely easy to use. however some date fields do not have the "calendar" option, so you are forced to manually enter the date. That could be made easier.
