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

I have tried a couple other products and they do not compare with the ease of the PDFfiller product. I am over 80 and faced with a great deal of medical paperwork regarding insurance, test results, doctors paperwork and hospital paperwork. My handwriting is a bit shaky with age and at times people can not read what I have attempted to write. I used PDFfiller on a several pages of a doctor's information form and it was a breeze and people could read my answers. The doctors staff wanted to know how I did it and thanked me many times for doing it with PDFfiller.

Solid, provides the service you need Easy to use. Mostly used for inserting signatures. Sometimes the signature block format gets distorted (inserts as a code).
