I may be an idiot but it isn't the most intuitive experience I've had. I have been under pressure to produce so that may have something to do with it.

Product is very easy to use! Sam, CSR# is 13005, is a very valuable employee & should be rewarded for providing A-1 customer service. His persistence to solve all & any issues, explain everything in detail & make sure I was content before ending our "chat session" was extremely appreciated, thank you for hiring someone that gives that high quality of customer care~

I am taking online college courses and this has been a miracle for me to fill and physically sign forms, I have a touch screen computer so I can physically sign with my finger. Really love it.

What do you like best?
The best features are (1) the ability to easily import and that it converts with accuracy and (2) the ability to manipulate doc - more specifically merge, edit, copy, etc.
What do you dislike?
The only feature that does not seem intuitive at times is the folder structure and how the files are organized. When editing a doc it will always move a doc to the top because it is the most recently viewed or edited doc - but this sometimes makes it confusing. Similar to Outlook, it would be nice to have easier drag and drop feature for organizing the docs.
Recommendations to others considering the product:
This is a quick out of the box product, overall very intuitive and easy to use.
What problems are you solving with the product? What benefits have you realized?
Able to import and edit docs as well as having them signed online.

Excellent PDF conversions This software helps me keep documents in unchangeable forms so that they can be sent out and not altered. I love that I do not have to download anything to my computer. I can go straight to the website, upload my document or file, and then have it converted into a PDF within seconds. It is super fast and the PDFs look great. I have used PDFfiller numerous times, and there is not one thing I can think of that I do not like about it.

Slight misunderstanding promptly resolved There was initially a slight misunderstanding, however, I was lucky enough to get Dee again when I reopened the chat. She had thought that I just wanted my subscriptions automatic payments cancelled. Really I wanted the payment stopped and the subscription cancelled. Thankfully she worked up until the last minutes of her shift to help me. She was excellent help!
