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.

Adobe for Life
Overall, it's an amazing feature of the Adobe family that comes in handy for myself and especially in my industry where contracts are signed and requested frequently.
So you're working on a project, job, whatever and you get a form that needs to be filled out, signed, and returned. It's a PDF file which is great because nothing can be edited off the original form. You're only responsibility is to fill it out and send it back, but you don't have a printer available, there's no fax machine around, and this form needs to be completed ASAP. The PDF filler is an amazing tool that gets the job done. Not only does it allow you to fill in information on any PDF file, it also allows you to upload your signature to docs as well.
So while you can add your information to any pdf file, some of the files don't always allow for ease of filling out. For example, some forms allow you to type into blank spaces where words and information are supposed to go, while others have distortion issues and don't always allow for certain spaces to be typed into.

I like it very much, I think it has great fearures and it has helped me a lot... so much that I was ready to become a paid user. However, 2 of the last documents I uploaded to the system were cut-off and seriously changed (different format, things missing, etc) the uploaded document did not show as an identical version of the original document and that made me change my mind. I use it for contracts and they need to be exactly as the original document. These are legally binding documents, so because of that, I decided not to continue the service after the free trial ends.
