What do you like best?
I manage customer service at high tech firms but at home I am just a mom. And every summer I have the nightmare of getting medical forms for kids to summer camps. Usually it is a real pain of printing the form, filling in the info for the kid, scanning it, faxing it to the pediatrician. This time I decided to try PDFfiller which I use at work, and it literally took me 3 min to do two camps! I just imported the medical form pdf, filled it in, and faxed it to the doctor's office right from the app. Nightmare no more :-)
What do you dislike?
Some UI feels non-standard. For example I could only save the pdf in my downloads folder rather than being able to select the folder I wanted.
What problems are you solving with the product? What benefits have you realized?
Primarily, filling of paper forms online, for example insurance and tax paperwork for new employees.

What do you like best?
It works. Easy to use platform. I've subscribed for several years and they continue to make improvements. I tried docusign and this was just as good.
What do you dislike?
I don't like that it won't link up with business accounts on OneDrive so I can't store my files on OneDrive. Really would be nice to have them fix that! Also for some weird reason, the system only can connect with personal accounts. Sometimes, it's not easy to find my documents. Finally, the plug-in for Chrome doesn't always work well. Usually, it's just better to go into the app itself.
Recommendations to others considering the product:
Compare the functionality you need to what it offers. I suspect you'll find it's sufficient.
What problems are you solving with the product? What benefits have you realized?
Send out paperwork for signatures and fill out paperwork online instead of printing, signing, and scanning it.

Excellent support and customer service
I registered for an annual membership, but I didn't pay attention that the membership fee is calculated in US dollars. I live in Canada and it was expensive for me. I emailed support department to cancel my membership and they responded in less than an hour and sent me a full refund.
I appreciate the excellent customer service and proper support, polite and professional behavior of the staff.
