Very Satisfied and excellent customer service. After a charge dispute, the error was fixed immediately. Then had a print problem and that problem was corrected before I could explain to CS. Great service!!!!

The pdf filler has been excellent to use to date. I haven't explored the other options available, such as sign and send, although, I will definitely look into a full options account. Cheers.. Millway Security Scott Miller.

Loving the tool. It would be great if you could add an eye dropper feature so that if I alter text or numbers that are over a color background I can erase the copy fill in the area with the original background color and then revise the copy over the background fill

Very Helpful Filler This software is the answer on my problem before on how to edit the PDF. It is very helpful to me and to my team. Easy to access and easy to use. Sometimes I experienced the slow loading of software but it is totally manageable to make it better.

The software if very intuitive. No wasted time trying to figure out how to use the software. Not having to update the software periodically or pay high Adobe license costs. Drag & drop features and drop down menus work flawlessly. I can have a colleague use the software and not have to explain how to use it. May be thatI haven't had time to really look at this, but I find that I have a lot of information in my main folder. Intuitive or simple organization structure would be nice. I'm usually in and out of there to get what I need done, but I did have to search a few times and thought I needed to clean up that home screen.

I LOVE the features in the premium package! Now I can create a fillable form and put it on my website where it can be filled out directly! I can even customize the button they click on to fill out the form! I added radio buttons, check boxes, and fillable text boxes. I even saw where I can collect payment upon completion of a form. Great job PDFfiller.com for all these amazing business features! Brainmavens.com has become so much more user friendly thanks to you guys! -S.Farris
