First time, so experiencing a few problems learning your system. Need to spend time learning how to make it work best for me. Will just have to figure it out for myself.

I am using it on free 30 day. Until now, working great!! The best part is how I can literally edit any text that I wrote just by click and it is super easy to make changes to any text that I write using pdf filler.

I really liked the variable size eraser. I needed to send my bank statement out and I did not feel the party needed to know my balance when they were only looking for a particular debit.

What do you like best?

What do you dislike?
Really no downside. I do find it takes a long time to merge docs, but that's really no big deal.
What problems is the product solving and how is that benefiting you?
E signing docs. Editing PDF's that were sent to me on my computer without having to scan the doc is amazing
