I needed to type on an older document and this program seemed like a good choice. Also, since I can pay month to month I can stop when I am finished with the paperwork and that was a nice option.

I had a difficult time with it and it took a long time just to fill out passport forms for my wife and I. I just could not get the hang for it, but someone smarter than me and maybe younger, I am 72, will do much better with PDF filler.

It takes a minute to get use to but I think I'm getting it. Trying to use to send files to the government. I was trying to figure out how to just save a pdf filled out.... there are so many pop up windows.

The price should be mentioned up front. You have to pay at the end because the document is important. I'm sure that is intentional. Its a good program so far. I will let you know the final outcome.

So far it has been fairly simple. Am glad to find the form I required and has been pretty simple to fill it out. Will be back to finish as soon as I compile the other information required for the form I am filling out.

So helpful. I can fill out the form instead of scanning, printing, filling out, and then scanning again so that I can send it back. I did try other programs... this one is by far the very best.

I had an issue that was my fault and it was taken care of immediately. Even late at night. I was very worried that there was no phone number or email to contact them but they replied quickly through their live support and took care of my issue and fully refunded my money. Thanks.b

My only knock is the price My only knock is the price, for a small business this is an unique tool to have to save money getting documents done over etc. If the cost was not out of my price range, for the amount of time i use it i would definitely purchase.
