I worked fine for my needs of filling in a PDF file and saving it with data. I would like to see the ability to CREATE a fillable PDF file that I could distribute to others to fill out, save, and return to me.

Do you really want me to tell you what I think about PDFFiller? I am about to jump out of my skin with this program & I just started using it. I have not used hardly any of the features it has! Sending me a follow-up survey is not going to only do one thing? I'll tell the world how excellent this software is!

I like it but felt that my "free trial" was a bit of a scam. I spent hours on a document, learning your program but was unable to print it. I don't like being "forced" into purchasing a product.

It works and is easy to use. I think it is a little pricey for the occasional individual user. Would like to have options based on degree of use: e.g., individual vs corporate.

I am very happy with the customer services of pdfFiller. I am very happy with the services of pdfFiller.com Their customer service is excellent. A payment was automatically made from my credit card. However, after talking to the customer service, I got my refund which I never thought would be possible.
