Just getting started. Signed up a few months ago but it is only now that I am getting around to cleaning up my forms for a virtual behavioral medicine practice
I am very impressed with PDF filler and its features. i am not the most computer literate person and i do have a bit of trouble navigating around the program so a demo of some kind would help me a lot if there is one that i can watch. I guess its just a case of playing around with it but there's probably loads of easy shortcuts that i could use if i knew about them .

I tried the software and then cancelled it. For me it was too challenging to use. However they still charged my account for a year up front. I didn't authorize that. I called and requested a refund and they gave one right away, so they said. It was just today I requested a refund so I will check my account in a few days to see if they actually sent it. If you don't see a complaint from me here on Trust Pilot then PDFFiller honored my request. My name is MarioV.
This has been a great for filling my forms
This has been a great help with the forms I am currently working with. It does sometimes freeze but usually if I close the program and reopen, it works fine.
