Works great and has all the features I required. I have found the customer support to be really prompt when I have had inquiries. Definitely going to keep this past my trial period.

What do you like best?
Easy to use, anyone who I've sent a file has had no issues receiving and downloading. Some of them have told me they've gone on to use the product regularly themselves.
What do you dislike?
Nothing to do with pdffiller, but I sometimes forget to set up the files I'm uploading in the right folders. That's on me.
What problems are you solving with the product? What benefits have you realized?
Under the 'documents' tab, the 2 columns on the right could be made more distinctly different from each other to denote they are in fact different. They are just two shades of gray and not that different in tone.

PDFfiller is the best, hands down I've used just about every PDF filling service I can find and although PDFfiller is on the pricey side, I've found them to be the best because of their drawing features, beautifully organized website on both desktop and mobile, and super fast customer support. If you need to fill out PDF's regularly, I'd say PDFfiller at $6 per month is easily worth the money.

This is my first experience with online documents and I had a difficult time maneuvering through the settings. Would like more information on how to use.

Customer support was very quick to reply to my issue. I had been charged for my pdf and wanted to cancel as would not use the service enough to justify $96.00. In reply I was told it would be cancelled and the automatic renewal deleted. My only regret is that my money would not be refunded.***** to the charge I had tried (unsuccessfully) to find out how to cancel it. Im either stupid or the instructions werent on line.to easily find.
