I am very happy with PDF filler. I have only used it for one document so far, but I have no complaints except for the pop up every time you open the form.

It's very good and I recommend it to others. I know I am not getting the full benefit, and should attend a webinar but feel too busy unless it could be archived and watched at my convenience.

The only issue I had was I had to complete it all in one sitting. Even though I paid for the sertvice it wouldn't let me save it. I started the document 3 times and lost all previous info the first two times.

I really like working with the filler although there could be better control in the editing. I believe it could be more intuitive as to the fields which are potentially fillable and place the cursor within those lines automatically. It is fussy to try to line it all up.

Very pleased with the customer service I recently moved from Nitro to pdfFiller and just had my first customer service interaction. I was very pleased with how promptly I received answers and how well my issue was resolved. Off to a very good start!

I had a billing issue and customer… I had a billing issue and customer support identified my problem and solved it with ease, no hassle, and immediately. Just good customer support. That makes the entire experience worth it, and the product worth paying for in my opinion.

I really enjoy using PDF filler. I consider my self to not be computer savy at all. I would really like it if there were a webinar to help people like me understand this app.
