I have been using the free version for a few weeks now to try it before purchasing. It is not very impressive! The speech to text is awful! I am doing medical transcription files for a test and it is talking about Russia and other crap, and it's not even in sentences that make sense or anything close to what is being said! I am not going to purchase and pay for something this terrible!
I have been having issues getting it to work with sound and the pedal.
