Just getting started with some of the applications, but so far, so good. Definitely beneficial in replacing lost forms. Looking forward to other uses. Maybe survey another time. Thank you.

The obne drawback I find is when I am typing into a field there is no auto return and I suddenly am skipping to other fields. However, it is still a pretty good product.

Quick to respond to email. Quick to respond to email.Most of the time when you send an email, it goes out and either no response or very delayed response. NOT so with PDFiller, they responded to my question quickly and took care of the issue. I am very happy with the response as well as how efficient they were. We are signed up with them and will be a great customer of theirs.Peter

Love this!!! Can erase words from PDF's. You will love this program!!! There is an eraser feature that is the best thing ever. This allows you to change a PDF document. How many times do you need to modify a document, or wish it said something different, but don't have an editable version. With PDFfiller you can erase the verbiage, and replace it with something else. You can also easily place your signature on documents too. You can upload you own personal signature too.

pdfFiller has wonderful support. You can email them or use a chat feature. From the chat feature, I was able to do a remote session through zoom to get my issues resolved quickly. Through email they always respond within 20 minutes. Great customer service!

The only complaint that I have is that… The only complaint that I have is that in the editing section it isn't user friendly. For me I had to just rewrite my whole paragraph since it wasn't easy to just copy and paste! Otherwise I am really pleased with the pdf revise site.Jacqueline Radell- McRaney

The product is very good and it works very nice and it's very easy to comprehend how to use it, but the way you have the purchase setup I feel is very misleading I signed up for the month the month payment and you took a full year out of my account I did not like that that is why I would never recommend your product to anyone want to use because you can really mess up a person and you could be taking money that they could not have to be taken at the time. You need the fix your payment process area or you will lose other customers like myself because I did report it to the Better Business Bureau cuz I did not appreciate that.
