Was a bit cumbersome. When I searched for forms, the system kept giving me instructions on how to search instead of stating that an error was made or what to do to continue.

App produces error during install for smartphones. Should favor browser entry, or at least make link more prominent. Also, the way that some of the advanced features are not available to a subscription is a bit misleading they way they are presented IMO... At the very least, the base subscription should provide limited quantities of some of the more advanced features... (monthly counter etc.) ~ Because the casual user may really benefit from these features (in low volume.) And there's little incentive to not just "get by" with the free services if they're not available.
Bob T
Just an amazing product and service. It has made managing and editing/updating PDFs a task i am no longer dreading to do. It has saved me SO MUCH TIME and headache working with PDFs.
Ty O
PDF Filler is great. I started with the free trial, then went to the pro, but now I've switched to Basic. I got this for signing contracts on buying and selling my home. Awesome!
Melanie C
At first I had difficulty understanding how to use PDF Filler maybe because the way the dashboard was set up was that there were too many icons that made it seem too overwhelming.
Lisha F
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 .

Logging issue troubleshoot I was having issue logging into pdfFiller with the password that I remember, at the same time could not receive any email to reset my password. Harmhon, the live chat agent from pdfFiller, has patiently understand my situation. Although most of the time is user's issue that they don't check on junk mail or they have some instruction/rules listed in their setting. But Harmhon is able to figure that my email address was actually not being whitelisted in your company whitelist. That being said, after Harmhon inserted me into the whitelist, i am able to login without any issue again. I really appreciate Harmhon's patient and service. He is definitely a precious asset to pdfFiller! Keep up the good work!

I am really pleased with the help that… I am really pleased with the help that I got it from the live chat pdf support. The person name is sam and he was very helpful in solving my problems. I would like to say a big thanks to him.

It's kind of quirky, because I[m not familiar with pdfFiller and it just pops up all of a sudden out of nowhere, so I don't know where to begin.
