See for yourself by reading reviews on the most popular resources:
I have not been able to figure out how to use my mouse and just scroll/roll thru the doc. I have to go to the left and click on page 2, to get to page 2, I can't just use the roller on the mouse to move.

Not for free to send it and save to computer. Almost $7 for a year isn't bad though! But I'm not sure if i'll be using this all the time though throughout the year.

This is a tool which I never thought I would use so much! I love it! I think the dashboard is cluttered and not the easiest to navigate, and a "strike through" option for documents would be nice to have.

Top notch support team!
I want to start by saying that this program exceeded my expectations! It not only delivers on everything it promises but goes above and beyond. I used it for a marketing class, and it made the entire process seamless and straightforward. When I encountered a billing issue, the support team resolved it promptly—even during a holiday weekend! While the PDF filler functionality is outstanding, I’m even more impressed with the exceptional customer support. Thank you very much for the excellent service!

I have found this PDFFilter writer and downloader to be exceptionally useful and user-friendly. It organizes my files clearly, making navigation simple and efficient. Additionally, the integration with Dropbox and Google Drive, as well as the ease of downloading files directly to my computer, significantly enhances its convenience.

Easy to use
Easy to use. I wish I came across this solution first because with it I was able to do in 10 minutes what I couldn't do in hours with the other editors I tried, not counting all the time trying to find them.

PdfFiller is truly worth it!
My overall experience has been amazing. PdfFiller is user friendly and pretty affordable too. I use this software to edit and sign work documents, so it has made my life a lot easier. I would recommend this software to anyone and everyone!
I love the convenience that PdfFiller gives me. I love that I can easily edit my documents without encountering any problems. It saves me the time and admin of having to download, manually filling-in documents and scanning them. My work documents look more professional.
I have not experienced any cons as yet ever since I have started using this software.

Still learning and having a few problems, but probably user-error related. Would undoubtably help if I had slowed down enough to watch the video, but just had to get this done.
