Great; better than it used to be. Used it many times in my pursuit of Real Estate. Write the contract, print and scan to the seller. Really Nice; economical; my attorney even asked about it; he's addicted to it now, too.

I absolutely LOVE this program. However, I hate the pop-ups with the NEXT button. This isn't a feature that I need, and is very annoying. Please add an option to turn off this feature.

So far, so good. Nice feature that long ago MS in word offered something similar. If marketed correctly, it should be very successful - God willing.

Initial problem was apparently that I had failed to save the (almost) completed form that I had made, and when I went bace to it, only the original blank form was available. I see the error of my way. Quite interested in learning lots more about program and the ways it couod be useful to me.

I like using the program the only downfall for me is unless I pay more for the subscription I'm not allowed to use the premier options. That is my opinion It's already expensive for me since I really only use it for tax returns.

PDF Filler was easy to learn and use, I was able to get the signatures I needed, very satisfied. The only thing I was unaware of (could have been in the small print) was the trial obligation before being able to download my signed document. Overall Great experience.
