Beware that use is strictly limited.
Beware that, even if you purchase a license, the program is limited to a certain number of uses per day or per week. Beyond reading the standard terms, you'd have to read every word on every page of their website to discover all the limitations. I hit my limit after 100 uses during what they call a "natural week," whatever that is. That made use of DVDFab much more difficult for me as I had to break down my hardware and set it up again a week later to continue. I was refused any kind of adjustment or reasonable explanation other than "read the website."
