I like that it is easy to use, has many different templates available so you are not limited by what they provide or how difficult their interface may be (if any).
It's also very affordable compared with other companies out there! Nothing really - just make sure your computer meets all requirements before using this software because some computers have difficulty running medical transcription softwares without errors/bugs. We needed an easily accessible way to transcribe our doctors' notes from handwritten documentation as well as having them sent directly through email when finished instead of going back over each note individually which was time consuming.
