So far it's been pretty good although I haven't figured everything out yet as far as the features but I'm working on it. I like it so far though for what I needed it for. I will continue to pay for my subscription and continue using the service. Thanx your service has been and will continue to be a BIG HELP to me.

It took a few minutes to learn navigation, but once figured it out all is good. Still many features that i have only scanned thru that really look very helpful.

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 :)

Great Tool!
My experience has been great thus far. The use is seamless whether on my tablet, laptop, or phone, however, it's much easier to use on a laptop due to screen size.
I am able to conduct business, receive faxes, scan items, edit forms, and more while on the go. This makes life a BREEZE! I am never really disconnected from work unless I choose to be.
I would say the monthly payments are ongoing and never end. In real life, things like software have a finite value, however, I haven't seen an all-inclusive tool for less.

Great tool for PDF mistakes
Good experience, I really recommend this for people who need a PDF edit tool
It' easy to use, few and useful settings that can really help fix a mistake or even save the document in a different way
I couldn't find the go back tool for a minute but it's actually pretty simple and helpful

I liked the flexibility to edit and make changes in my document.
Its rare to get something like this, especially for a pdf format. for me it made things easier as I was working on a pdf document and I wanted to make a few changes on it without converting to a word document.
