See for yourself by reading reviews on the most popular resources:
I have only used this once so far but it was very good quality. I hope to be able to utilize this program often. I just wish it could be put on my desktop.
2014-05-29
I really like the ease in using this program. I have tried other PDF software but find them all very awkward to use. I am just not sure about the pricing. I assume I signed up for 12 months? This is a great program and I don't have to hand print documents when most documents are PDF anyway.
2017-02-04
I absolutely LOVE this program. However, I hate the pop-ups with the NEXT button. This isn't a feature that I need, and is very annoying. Please add an option to turn off this feature.

What do you like best?
Easy to use but comprehensive options for editing. Quick and efficient which is important with time sensitive docs and a busy life. Some recent new features tells me the company is progressive. I was having technical difficulties one day and support was responsive. I've tried numerous PDF/Editing programs. and this is by far my favorite. It's web based not some ap that you have to download that later crashes your computer. Can access it from any PC so that helps too.
What do you dislike?
The price is substantially more that I'd like to see. Takes a bit to save file to PC once done editing. can be a little slow at times but still a reliable tool I use at least weekly if not daily. Something in the $50 range would be delightful and it's well above that currently. Maybe efax for this price I have not used the esign feature yet so maybe will try that given our member benefit program is lapsing.
What problems are you solving with the product? What benefits have you realized?
Quick way to edit and correct documents. Easy to save and access later. Lots of options for composing sending and revising. I only use basic functions but there are several ways to use this valuable tool beyond the features I use that exceed other competitors.

It was wonderful to use so I didn't…
It was wonderful to use so I didn't have to go to town to fill out the particular paperwork i needed to turn in. The only negative was I thought I was in a 30-day free trial period, and I was charged two separate charges, though they were very small, but yet I was charged.
