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.

Great App I have used this product six times since installing 2 days ago. This is the best PDF app I have seen in a long time. I will highly recommend it.

The software is really good The software is really good, haven't tried the customer service yet.My only main issue is that it deals with the text as line by line and not as a block of text, and sometimes it when editing the text it makes it smaller automatically just by clicking on it.This makes it a bit harder to edit at some times but will see if it affects me much or if I can find a way around it. The rest is really well organized and efficient.
