pdfFiller scores top ratings on review platforms
LIKED THE ABILITY TO SAVE AND PRINT BUT IT TOOK SEVERAL TRIAL AND ERROR EXPERIENCES TO FIGURE OUT THE PROCESS. SOMEONE WITH VERY LITTLE COMPUTER EXPERIENCE WOULD FIND THIS FRUSTRATING
user friendly, easy to create and send, very happy with the responsiveness of customer service via email; however, it would be nice to be able to speak to someone on the phone for quick questions.
Simple and versatile. Since it is new "technology" for me, I must use it with some guidance to understand all its utility, so the tutorials that are included will be handy without having to go to school to learn it.
Working great for filling out forms
Working great for filling out forms, on my phone or PC saving and printing. However, trouble signing in when opening file from email and works more smoothly if signed in before opening.
