At first was a bit different in look and function but after a short time became very easy and logical to use. Still wish you could print directly from editing screen.

Initially, I wasn't too sure on how to use the various features and tools available. I took my time to read each area carefully, used the "help" icon. Very pleased with the results of todays work.

Error in my ways!
I was unaware that I had used the service in the past which voided out my free trail. I then subscribed again and was instantly billed for a full year. When I realized my mistake, I reached out via instant message to the support staff. The service was stellar at best. They assisted me promptly and corrected my dispute which was impressive to say the least and speaks to the integrity of this service.

I needed a straightforward way to file…
I needed a straightforward way to file an extra tax form, and PDF Filler helped me out! Much easier than finding the form on the IRS website (somehow impossible?) and hoping for the best.

Reasonable but not fantastic
Pretty decent, I'm not sure it's the best PDF software available, but it's not bad and can complete most tasks you'd ask of it.
The software works for the most part well and allows the signing and creation of forms, handy for mild administrative use.
Support seems limited to live chat only, which is a bit of pain if something goes wrong. It could also do with a mobile app which I don't believe there is currently.
2021-01-07
There are some minor things I have not figured out how to do. Not sure yet if they are just missing features, or just not readily available in a way that I was expecting.
