The obne drawback I find is when I am typing into a field there is no auto return and I suddenly am skipping to other fields. However, it is still a pretty good product.

I had difficult printing what i had written on a PDF. Although customer service was EXELLENT I still could not fully implement their detailed instructions.

We have had a service application on line for several years. People have been printing, handwriting the answers to our application and emailing it back. I just received back my first fillable application and I love it. It is legible and all the answers appear where they are supposed to no more writing up the side of the page because of the limited space for answering.

I had to type information into a PDF document and I couldn't do it in Windows 10; I found pdf.filler.com and was able to type in my information easily!

It includes everything I needed to do, and then some. Its much more user friendly then even Adobe itself. But, for the price, and my specific needs, it works great.

I was able to find any form that I needed to fill out. PdFiller was instrumental in helping me fill out additional tax forms needed to file my taxes. All the forms were there already! There's even away to have your documents sent/mailed to the intended party! I wish there was a way I could have a subscription for a much lower amount that's based on my usage. Right now the price point is decent for a person that uses it frequently like multiple times a day.
