The service is great and has come in handy in ways I had not expected. However, you lose 2 stars for my initial experience of first being asked to to pay, by a pop-up, to see a form that was submitted and then after paying being told by another pop-up that I need to upgrade to a more expensive plan. The first pop-up should have presented the correct plan. Felt a little like a bait and switch. But I gave you back one star due to the fact that support was able to fix the problem, quickly.

I am in a struggle with the Home Office. I have to fill out multiple forms repeatedly. I bought Adobe but it did not work. This software is very straightforward and I am sharing the document with my Barrister, which saves me money, time and avoids confusion

My life is so much easier with PDF… My life is so much easier with PDF filler. I can instantly complete any paperwork I have. I was able to figure out how to use it without reading any instructions at all. Even better, I am saving cost and waste of printer and paper.

I love the PDFfiller, I find it very easy to use. It is making my newsletter each month alot easier to create. I am able to erase words that I don't need & put in the ones that are easier to read. I have some PDF's that are very light gray print and don't copy very well. I can take out the words that are too light & replace them with clearer, larger, darker letters. It is easy to go back to change anything that is not what I want.
