I am so happy that I found this. It makes completing so many forms so much easier. Additionally, I've got forms that must be completed that are now no longer fillable through the agency that created them. This will allow me to continue to fill the forms.

They have great customer service I was… They have great customer service I was refunded when I didn’t realize i paid for a years subscription upfront and I only had to pay the first month. Very happy companies like this still exist. The file editing is easy and can be done from iPhone.

I think that it's a great thing. It makes fighting a case much easier. That more people don't use it. There is nothing else that I like least about it. My vice president used it also an has no problems with it. Being able to find what your looking for, then being able to fill form in an save it, then come back to it.

Kara was spectacular Kara was spectacular! I was having trouble merging 35 small PDFs into a single larger document. She walked me through all the steps, and I told her what I had done and where I had run into problems. When she could not find a solution for me that way, she offered to merge all the documents for me!!! I have been working on this family project for the last 12 months and this was the final step before I could get the finished document out to everyone. Now I can do that and put this phase of the project behind me! I salute you Kara!!!
