ITS PRETTY GREAT, THERE ARE A FEW FEATURES I WOULD LIKE, INCLUDING AN ONLINE MANUAL AND THE ABILITY TO MOVE TEXT BOXES ONCE THEY ARE FILLED OUT. THERE COULD ALSO BE AN ABILITY TO PAY PER FORM AS I PROBABLY WON'T BE FILLING OUT PDFS FREQUENTLY ENOUGH TO JUSTIFY MONTHLY PAYMENTS.

I like the site and the program. I do not appreciate being told of the cost until I had invested significant time filling it out. Not nice. Felt compelled to buy product - not fair. P.S. Even though I felt I had to buy it, I like it and have since used it multiple times.

This is an excellent tool to use to complete paperwork to save and email or fax back on the fly. You can print afterward, or as soon as you complete your paperwork. Saves so much time, and paper, as you don't have to print.complete.scan and then send.
CheryD
the service is great, however the payment option is miss leading, as it says $6/month and when you go to pay you charge the full year up front, in US$ and some of us are poor, so thanks for that.
brandy
The site is a bit slow, and often will freeze during filling. Otherwise it is well worth the $72.00 I paid although it was supposed to be a free trial for 30 days.

Program makes editing PDF files easy Program makes editing PDF files easy. Update standard fields is a piece of cake. Getting familiar with program was fast and easy as well.

The person who assisted me was Kara and she was absolutely friendly and was not only able to help me resolve my issue but also respond to my emails promptly! Really thankful and appreciative of her help! Truly great service by her!

I'm working on several files for which I need to be able to type in the answers as my hands have arthritis in them and that makes it difficult to write. The instructions could be a little clearer. To be honest, I'm a new widow and I wasn't thinking very clearly. I haven't taken the time to read the online instructions so my navigational issues are of my own neglect. I think you have a wonderful product actually.
