I have had limited use since I became a subscriber. I have difficulty printing the PDF file I was working on and asked your online help desk what I could do to remedy that but without success.

What do you like best? How easy it is to access all documents and edit previous documents What do you dislike? I wish there were more tools to help edit, such as cropping a document or resizing What problems are you solving with the product? What benefits have you realized?

I had an occasion to need a form filler on a ***. I found PDFfiller online and tried it with a trail. It did exactly what I had wanted and it was easy to use. I guess I forgot to cancel the trial so it did go into an annual charge. I dont need a *** form filler on an ongoing basis. When I saw the annual charge on my ****** account I called immediately. I explained what happened and they immediately said they would close the account and refund my money. No hassle just very polite support person and efficient. Should I ever have an ongoing need of a *** form filler I will absolutely buy PDFfiller. It works and they believe in customer support. A rarity today.
