In my opinion this application is very powerful, however not so intuitive, and I had to spend an inordinate amount of time in chat with technical support personnel. I would be happy to explain further.

It was very easy and it had help listed if you needed it. So, I felt it was a great system to use and I will be using in and have used it in the past but I don't have Verizon anymore and I forgot my password. So I just created a new account.

I was disappointed with the services I purchased, but PDF filler made it right and refunded my money. I appreciate how attentive they were to my needs and what I was looking for.

It's not as easy to follow as you think it is. For example, Save As is a command that most of us think as a file name, not application such as PDF or Docx. I now have to go back and find the document, add the signature and then, change the name of the file, somehow from the template to a specific client's file.

What do you like best? I enjoy the ease with uploading and editing files. As well as, the ability to change file types or combine documents. What do you dislike? The formatting can be time consuming and is hard to keep text consistent with original document. Recommendations to others considering the product: I would consider what you need it for and the price. It serves a good use for pdf editing and file management.
