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.

What do you like best?
PDF Filler is super simple to use. I love that you can just click where you need to put information (whether it’s a checkbox, words, etc) and it’s done. If you have a form that you use often you can even save it as a template so you don’t have to go back in and create new boxes each time.
What do you dislike?
I’ve had a few issues with the site being down but this only lasted for short periods of time. Otherwise, the product itself is fantastic.
What problems are you solving with the product? What benefits have you realized?
Instead of needing to print forms out, we are able to fill them out online, at a cost effective price. Saving us paper, ink and time.

They could improve the user interface to be more user friendly in some ways.
What problems are you solving with the product? What benefits have you realized?

Wow! Finally a real online PDF editor, no more troubles on changing text and much more! Just found it randomly, and since the beginning it shows me lots of features to edit pdf like texts, images, signs, highlights and more. The graphic looks a bit oldie, but this is not a problem at all. Functionality first! 30 days trial, then you've to pay.
