Have been able to add signatures change dates and update pertinent information on the documents. Have not used extensively, but have been able to do everything I wanted so far. Good product!
Clem
So far, so good. I love the fact that, before I paid--my documents were always saved and not lost. So that later, when I was ready to pay, I didn't have to start over. That was awesome.

So far it has been frustrating ( just because I am not tech savvy) I am just trying to reprint a pay stub that I have lost from a former employer and I just keep running into problems. However after watching a video I figured it out without a problem. Customer service is A1.

They were very nice about it with no drama. This would be the company to choose if you need the service! Thanks again for your fast email to to cancel and refund!

Life made easy If you fill a lot of forms, it is worth it. Otherwise you might not want to pay for the subscription for just one form. It makes editing and filling out forms so quick. The tools are great and the UI is easy to use and clean to look at. Once you fill the form, you have to pay or else you cannot save or print. This is not made clear from the start.
Erica L.
Negates deciphering handwriting When filling out or reading an application or some other such document, it is hard to manage legibility. The ability to type directly into the fields of a PDF is a valuable option to avoid that. I wish you didn't have to create an account to use it. It would be better in my opinion if you could use the software with out having to do that.

I'm a little bit new at the process, but I'm interested in learning as much as possible about any new technologies, that will save me a little bit of time.
