What do you like best?
The best feature of PDFFiller is its ease of use, whether it's editing documents, signing documents, and then being able to access your documents anywhere by logging onto the site, as opposed to being constrained if you don't have your computer files with you.
What do you dislike?
Some of the option menus should be improved upon, especially as far as layout and ease of finding what you need, it's a bit counterintuitive though with experience that becomes less of an issue.
What problems are you solving with the product? What benefits have you realized?
Signing PDFs with ease. Being able to access and edit a pdf no matter where I am as long as I have internet access, even if I don't have my computer with me and/or don't have access to my cloud storage.

It is difficult to find the exact years…
It is difficult to find the exact years form. For instance, I searched for 2019 1040 SE and I got a lot of 2014 forms. I had to over search for the correct form.
