Awesome, I love it,I am a disabled Veteran, retired from the Navy and working with the VA many PDFs are used, this makes it so simple and the ability to take a picture of your signature and use it on document is great!

You need t tell people that if they enter numbers with commas, the IRS filing process does not work. After lots of time and trial/error, I stumbled across that as the cause of my problems.

So simple to use
I regularly have the need to edit & sign documents & have used a few of the other free & paid services, PDF Filler has been great to work with so I renewed my subscription again..
I find importing a PDF easier than most other similar softwares... changing font sizes and styles is simple and the process is fast even on my slow internet service..
So far I have not had an issue with any of the features..

Takes a little getting used to, but not bad
Fairly easy to use once you get used to the set up and lay out. I had used different software to begin with so it took some time to get used to. I like the fact that you can create or upload your document, fill it out, sign it and then send it off to be signed by another party all in one place.
Took some getting used to as I had used different products in the past. Other than that, there really is nothing bad about this software.

Excellent Customer Support
I received quick email responses from costumer support and very fair and kind help - I wasn't aware of my subscription status and was billed for a full year. Because I didn't need the full year subscription, I cancelled my subscription and emailed customer support right away to let them know. I requested a refund and it was kindly granted. Mind you, I emailed them as soon as I got my billing notification from PayPal and my bank account hadn't been charged yet - but they made sure to refund me before I was charged! Many thanks to the helpful customer support worker.
