I am a first time user and so far I have experience no problems. I have signed up for one month of service to try out actually being able to use my documents. We shall see...

The experience feels as if PDF Filler was really made with the end-user in mind. Everything I needed to produce a professional document made simple. Thank you.

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.

I felt very mislead, I entered a lot of info onto a form and was only told when I tried to print there was a charge. There was a monthly charge shown but when I selected the monthly option the cost suddenly shot up

It's a great experience and many options to get your forms completed in the manner you want them done. The option to save them for later and email them to others to edit is definitely a perk!
