Excellent features This allowed me to add to my PDFs that I couldn't before. This product saves time. I was trying to find something that lets me add a text box or even text to my pdf files. This product does this! Very cool! I can't think of anything. It does what I needed it to do. Excellent and easy to use for my documents.

I enjoy the feature that it has similar to PowerPoint. It helps you align your entries so that they look neat and comfortable for the viewer to read. The entries are convenient as I do not have to rely on drawing a text box. I would definitely recommend it to new users as well, as I am on myself. It Gives you a chance to try before you buy and has tools to help with almost all your legal questions and concerns!

What do you like best? Navigation is simple, editing works well and have never had any issues. What do you dislike? I really have not found anything that does not suit my needs. What problems is the product solving and how is that benefiting you? To edit design documents quickly by making quick changes. It also helps in editing quotes to clients.

Hi only needed PDF filler for one doc Hi only needed PDF filler for one doc. Trusted the site enough to add my credit card, used the program and then deleted the account. Seems like this business is legit and would use again.

Works pretty well.. I figured out how to use it without a whole lot of instruction reading. I wish the alignment in the form boxes could be made more accurate, I had to adjust many.
