It was really easy to use the very first time I used it. It is also cloud based so if I need to use it on a different computer, all I have to do is log in on that computer.

First time user who is definitely enjoying the ease of completing PDF documents without the troublesome steps to convert to a word or similar document for editing.
2016-09-06
free trial is great thanks but not sure how long i will need access for. I can cancel my subscription and thats great too but it means that i most likely wont pay the first subscription. Great for me but not for you. My point is, I would have been more than happy to pay maybe a "pay as you go" fee. Something like £2 to download for example, then maybe i would have to subscribe to use the other options available. just a though. thanks for a great site though :)

I like the way I can go back and make…
I like the way I can go back and make corrections and print out over and over until I get it right and not being charged for the times I have to print the document.
2021-03-09
What do you like best?
Ability to edit pdf files and general ease of use
What do you dislike?
Limitations on how many files I can upload and the fact that it opens the files immediately, If I want to merge a newly uploaded files with previously saved files on my dashboard, it creates some unnecessary steps.
What problems are you solving with the product? What benefits have you realized?
Not really any problems - just a few areas the program feels clunky.
