I find it so much easier to edit documents, and save for later. Being able to share and easily find them. As well as changing page lay outs for presentations too.
Noelene
I have had a great experience with PDF Filler. Being a computer novice however, some things were not quite as easy to find as I needed. I asked for assistance though and received it immediately. Great team !
Richard S
I used this program for one item in the past and just discovered today I can use it for many other types of forms such as Income Tax etc. Very easy to use, thank you. Wendell Juhl

What do you like best?
Changing things (like dates) on insurance forms helps us a great deal when the insurance information stays the same and only the date needs changed. (Accord forms). We don't have to completely retype an insurance renewal form. So Handy
What do you dislike?
I have helped a colleague in inputting his information on flyers that had someone else's and the eraser showed lines in the final product. I had to figure out what was going on and I figured out I could increase the eraser to remove items rather than going over it several times (like wite-out tape).
Recommendations to others considering the product:
If you need to make changes to documents that you do not want to retype over and over again, then this product is a handy tool. Also, for doing 'already-made-up-flyers' to use for yourself by adding your own information is great. I used to have to remake everything with Corel Draw. This is waaaaaaay easier!!
What problems are you solving with the product? What benefits have you realized?
Non really for what I use it for.
