I am only done with one of two multi paged forms.I was very thankful to be able to fill out some very long forms with a computer rather than free hand.

I am new to this program the search engine next to the description of the for would be great if you could see a picture of the for rather than having to click on it if it is not the one you want then back to the search engine

Just started using the program but have search many times before to find an easy way to access documents occasionally needed by our business. This format fits very well and will certainly increase the productivity of office hours. much thanks, Steve Rowell ( Brooks Carpet Inc. )

What do you like best?
I really like how I can fill out any form and it will turn it into a pdf. I also like how I can sign any form with my signature.
What do you dislike?
I do not really enjoy filling out forms that do not provide just a box to type in, rather it is little individual boxes for every letter. When the form is this way. I have to insert a new text box for every letter so that the letters would fall in their own little box and doesn't look out of place. These are the forms that are difficult to fill out. Unless there is a setting I haven't figured out yet.
What problems are you solving with the product? What benefits have you realized?
I am currently a law school student. There are a lot of forms I have had to fill out and PDFfiller makes this so much easier because I can just send them electronically to those who are alright with receiving them electronically.

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.
