I have tested it and every elements concerning my line of work are deeply thought out and very crisp. I had a problem of sending a folder but the solution is in merging the files to create one new file to send. The software is brilliant and less costly than all the competition I have tested.

I have not been able to figure out how to use my mouse and just scroll/roll thru the doc. I have to go to the left and click on page 2, to get to page 2, I can't just use the roller on the mouse to move.

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.

cancelled as a gesture of goodwill I downloaded the software and although it has a lot of good features, I didn't really need it. I thought I had cancelled right then, but I haven't found any more mail from me. Now the annual amount has been debited and I have contacted their support. After I explained that I didn't actually use the software, the subscription contract was subsequently and I was refunded the amount.
