PDFFiller
I like PDFFiller because it's easy to work between my Android phone and my computer. It's also extremely easy to email myself documents, reports, pay stubs whatever so that I can update them, edit them or have others sign off on them.
At times the program lags behind but overall well worth the wait.

Wish I Could Change Color of Signature
I enjoyed this tool and site. However, I wish there was just some way that I could not only change the font for my signature but the color to blue as well.

I love the app because it's very convenient. However, I found typing into the right spaces to be challenging, especially when I tried to align to them into the correct places.

I needed to use the service for an application
I needed to use the service for an application! It was only needed once. The day I was going to cancel it due to no longer needing the service the money had already come out of my account. They immediately refunded it and even offered a discount if I wanted to continue using it. I highly recommend it was an easy to use service with many benefits packed in.

PDFiller... Where have you been all my life ?
User friendly. Check!
Quality of software for your buck. Check!
Customer service that actual cares. Check!
Seriously. Look no further. PDFiller is the best thing I have ever stumbled upon!
This product is SO easy to use! I struggled with other software for my needs of filling in PDF forms. I stumbled across PDFiller one day while on a quest for software in order to do so. I looked NO further and started with a free trial. I instantly paid for the subscription no questions asked. I had found the program for me! If you have any conerns or questions the customer service is top notch and very helpful. Everything is labled for ease of use. I use PDFiller EVERYDAY! Buy the subscription .... you will thank me later.
Con: I cant draw lines on surveys with ease! That is something that I wish I was able to do. There are options to draw but no straight edge lines. That is really the only con that I have.

I'm happy with the use of the forms, however it showed a monthy price, so I was suprised when I was charged for the entire year up front. I only needed the product for a couple tax documents.
