Works fast and easy Works fast and easy, great service!I had signed up very briefly to edit some pdfs for work. The program worked smoothly, but then I foolishly forgot to end my membership, and was billed for a years' worth of their service, which I did not need. Their customer support was top-notch and had my problem resolved in just a few minutes. I'd recommend them for anyone looking for a company that is responsive to their customers.
