I really like the fact that I can download PDF files, fill them in and save them on my computer. Once they are saved I can then print them or go in and change them.

I really need something like this since I am partially crippled on my right hand and am right handed. This helps me alot with forms I need to fill out, too bad I have to pay.

Took forever to figure out it wasn't free. Here I thought I was filling out a form to print and filled it all out then said I need to pay. Very frustrating

It appears to be a good program and I intend to use it in my business and practice. One of the problems that I see is that there should be clearer explanations for some of the fields.

It's easy to use, I do like it; but it is a little expensive, $80/year is a lot. I use it maybe once or twice per month. I think you would have more customers if it was less expensive.

What do you like best?
I can sign paperwork, make changes and do it all without a printer wherever I am in the world.
What do you dislike?
There are some some glitches with the program.. for example to save a document you first have to make a duplicate of it. Also, I thought there was a way to re-number pages but that feature seems to be gone?
Recommendations to others considering the product:
Its a great program overall and affordable. I would definitely recommend it.
What problems are you solving with the product? What benefits have you realized?
I love being able to make changes to offer sign backs without a printer. Even if I'm in my office I still use it to keep the document clean and easy to read.

So easy to use and super convenient It's great to use. I love how easy it is to edit documents and it saves me time. I wish a few more features are allowable before having to upgrade.

Really fast friendly. Was really fast friendly. If i really had to point something out, it'd be that one message was in english and not the original langue we texted but I did not mind at all! Was a great experience, thanks you!

Super product, it takes but a few minutes to master and then you are off. The ability to change original self-fillable documents is a terrific feature.
