So far I have found every form I have needed. The only problem I have is that I cannot print directly from the website. When I try to print I get blank pages.

Amazing product! I was able to fill a tax form very easily and sign it. Better than all others I've tried! There are two comments for the development team and marketing team: 1/I expected a free trial, and 2/There are so many options that it can be confusing when you are just starting. I would have appreciated less options up front and some video tutorials to introduce me to advanced features.

It's hard when you start using it as there isn't a Pugh information on how to use it , so takes along time to do anything but you get the hang of it after a while, needs to be easier to navigate aroud

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.

Easy to use I couldn't do my job without this tool. I utilized this everyday as I create and fill out forms quite often. Its very simple and does not take any time to understand how to utilize the software. At times it can give you problems when you try and save and add certain things. I've also had problems copy certain areas.

Awesome! If there is a way to add your logo I could not find it... then again I didn't look either so...this might not be accurate. So easy to use. extremely user-friendly. The benefits are that you get to create any type of form you need and customize it to fit your needs. You cannot ask for anything better than that.
