What do you like best?
I like the idea that I can edit a PDF document that is not machine fillable. I have been using this program for several years now in personal and not for profit business.
What do you dislike?
This is not the most user friendly program to use. It lacks a search field or help section to answer questions as how to do something I do not know how to do. It would be nice to be able to save a document as you are finishing instead of having to go back and rename a document. This is the case when I am using a master form that gets updated each month. I work on my laptop and the print screen has the print button to low. I see a sliver of the print button, that if I mess around with it for a while, I can eventually click on it. I can't be the only person with this problem. It would be helpful if the print screen could open a little higher on the screen, reduce some of the preface before the print button or have the print button on the top of the form. I also get frustrated with getting an actual signature in the system. There are no clear instructions on how to do that. It took me hours and hours to get my signature as part of the program. It would be nice to be able to scan a signature into the program. I have used Adobe DC with work in the past and I find it is a superior product, but not worth the cost with the volume of paperwork I need to do. Also a typical example of issues I have with PDFiller is the instruction to take a screen shot of my log in page. I have no idea of how to do that so I attached a PDF master document I use pdfiller to complete each month.
Recommendations to others considering the product:
Don't expect to see the most beautiful documents as far as how things line up, but it is certainly a way to complete PDF forms typed instead of hand written,
What problems are you solving with the product? What benefits have you realized?
As I stated above I use PDF filler with forms that are not fillable. I have used them to complete tax returns when a fillable form is not available. I have used them to sign a document instead of having to print, sign and rescan the document before sending it back to the originator. I have not used it to obtain other peoples signature

What do you like best about the product? pdfFiller by airSlate saves me so much time when dealing with documents . You can easily share documents and ask for signatures via messages or even share them via QR code What do you dislike about the product? A bit tedious when it comes to editing the document. you would have to edit it in a word format and then proceed again with converting it to PDF format. It's a little bit too many clicks for my liking What problems is the product solving and how is that benefiting you? The ease of use is the major factor in using PdfFiller. It has help me communicate with the people I dealt with and send documents for their review and signature

It works - one problem I found though is that after I scanned a document with the Adobe scanner, the document was locked with password not allowing it to be opened by the person I sent the document to. I didn't seek that extra security so I basically don't know where it NOcame from.

Good overall experience pdfFiller does have a robust feature set for all document needs and the user interface was pleasant to use and mostly intuitive. I believe that a market for single users is far less likely since a normal user would not require most of the features that pdfFiller has to offer and they would probably not use the paid version. I would give 5-stars but you have to sign up in order to download your PDFS/Docs, i would recommend that you allow at least 2 Docs to be edited and downloaded before requiring sign-up.
