I was needing a temporary custody order for my grandchildren. I found exactly what I needed on PDFfiller and it made for a great experience. I will be using this product as needed in the care and control of my Grandkids life.

So far so good. One change I would like to see, when I insert check marks and x's on a specific row, they come out unaligned. WOuld be nice if they were all aligned

the biggest difficulty I have is when I am trying to re-order documents (move them left or right) -- it is just very difficult to see them. I wish the functionality allowed for enlarging the docs so that I could see what it is.

pdfFiller is a useful PDF editor and e-signing tool pdfFiller is a very easy tool to use if you find yourself needing to sign or edit PDF documents, but don't want to spend a lot of money on more expensive software. I appreciate how easy pdfFiller makes it to electronically sign documents or edit and convert PDF files. The instructions are easy to follow and within minutes you can merge, split or sign documents without to much effort. All in all I can't complain about the software. There were a few instances where I would download my signed document for it to turn out completely blank (in the free version), but then I'd just download it again and that usually solves the issue.

Overall pleased, have a bit to learn for my use which is limited home tasks. I believe that initial access problems are resolved. I am sure that I could more easily accomplish the basic tasks that I have for PDF. Not pressing and I can fumble my way thru it.

I usually use this program during a translation process when I get a request to translate a document in form of PNG or similar. But I believe that this app can still be further enhanced.

Prompt and honest. They answered my query online immediately and refunded for an incorrectly charged (not their fault) subscription fee within the hour! Was not expecting such prompt service and honesty to be fair, but so grateful they are honourable.
