Are you one that needs to easily sign documents and return by email? this is the software to use
None
I really liked how the software navigates you through the document so quickly so you don't forget to fill in any information, and it tells you if the recipient receives it.
It's supposed to have just about any document you would need or want but I couldn't find any of the ones I needed. It was frustrating trying to look for a document and not be able to figure out where the list was.

When I chatted with support
When I chatted with support, I had had two different people who took the files I had been trying to merge unsuccessfully and merge them for me!!! Similarly when I had trouble with blank pages and missing pages in a merged document I found out it was because I was using Edge as my browser instead of Chrome. It would have been best if that had been in the program itself, but support really came through to help me out.

Good value for price
When using the offer for roughly 40€ per year, PDF filler is a no-brainer when you need to fill in several forms a year for your household / family (e.g. insurances, real estate, etc.)

I wrote some legal documents using this…
I wrote some legal documents using this tool, it was much easier than other PDF editing tools I found. I was able to put my legal case together in an hour after wasting much more than that on other editing tools.
Excellent experience, terrific results.

I would love to attend a webinar eventually, but time right now does not allow it. I have been extremely pleased with pdfFiller and recommend it to everyone I know who has to fill out a lot of forms.
Maybe slower than hand writing , but legible which is extremely important. My biggest issue is somehow I have two accounts with other documents saved and do not know how to merge them. That was my problem not realizing i had an account already. Thank yall so much!!!
