What do you like best?
This just helps a ton when I need to edit a pdf on my computer. I used to export PDFs as a jpeg and edited the photo and it was super stupid but this is perfect because I never have to try to remember how I edited a PDF the last time I did it.
What do you dislike?
It’s a little clumsy and took a bit for me to figure it out, which means I’m not excellent at explaining how to use it to other people that aren’t technologically inclined, but it still works really well.
What problems are you solving with the product? What benefits have you realized?
I need to edit release forms and vouchers on a daily basis for my models and it’s a breeze with this extension on my laptop.

A bit difficult to navigate through/enter updates unless you use this on a regular basis. Once the memory kicks in, it's a GREAT tool for making easy changes/adding necessary information.

It's good
At first it can be a little overwhelming with all the options but once you get the hang of it is pretty essay. I really like that it saves all your files too, just in case.

My first time with this App and it seems to be a lot different to Adobe, but easier to operate. I have modified 2 pdf file successfully, and so far (as a new user), not too many 'dropped balls'.

It is great for what I am using it to do, however there is likely much more I don't know about yet.
After 2 weeks, I know much more and find the took extremely valuable. Don't know how I worked without it.
